simocode 3uf motor management and control devices 7/5 siemens lv 1 t 2006 7 simocode pro 3uf7 motor management and control devices overview simocode pro is a flexible, modular motor management sys- tem for motors with constant speeds in the low-voltage perfor- mance range. it optimizes the connection between i&c and motor feeder, increases plant availability and allows significant savings to be made for startup, operation and maintenance of a system. when simocode pro is installed in the low-voltage switchgear cabinet, it is the intelligent interface between the higher-level automation system and the motor feeder and includes the following: multifunctional, solid-state full motor protection which is independent of the automation system flexible software instead of hardware for the motor control detailed operational, service and diagnostics data open communication through profibus dp, the standard for fieldbus systems design general simocode pro is a modularly constructed motor management system which is subdivided into two device series with different functional scopes: simocode pro c simocode pro v both series (systems) are made up of different hardware components (modules): per feeder each system always comprises one basic unit and one separate current measuring module. the two modules are connected together electrically through the system interface with a connection cable and can be mounted mechanically connected as a unit (one behind the other) or separately (side by side). the motor current to be monitored is decisive only for the choice of current measuring module. an operator panel for mounting in the control cabinet door is optionally connectable through a second system interface on the basic unit. both the current measurement module and the operator panel are electrically supplied by the basic unit through the connection cable. more inputs, outputs and functions can be added to basic unit 2 (simocode pro v) by means of optional expansion modules, thus supplementing the inputs and outputs already existing on the basic unit. all modules are connected together by connection cables. the connection cables are available in various lengths. the maximum distance between the modules (e.g. between the basic unit and the current measurement module) must not exceed 2 m. the total length of all the connection cables in a single system must not be more than 3 m. simocode pro designed for mixed operation depending on functional requirements, the two systems can be used simultaneously without any problems and without any addi- tional outlay in a low-voltage system. simocode pro c is fully upward-compatible to simocode pro v. the same compo- nents are used. the parameterization of simocode pro c can be transferred without any problems. both systems have the same removable terminals and the same terminal designations. system simocode pro c simocode pro v modules basic unit 1 basic unit 2 current measuring module current measuring module or current/voltage measuring voltage operator panel (optional) operator panel (optional) expansion modules (optional)

simocode 3uf motor management and control devices 7/11 siemens lv 1 t 2006 7 simocode pro 3uf7 motor management and control devices function multifunctional, solid-state full motor protection current-dependent electronic overload protection with adjustable tripping characteristics (classes 5, 10, 15, 20, 25, 30, 35 and 40) simocode pro protects three-phase or ac motors according to iec 60947-4-1 requirements. the trip class can be adjusted in eight steps from class 5 to class 40. in this way, the break time can be adapted very accurately to the load torque which allows the motor to be utilized more effectively. in addition, the time until the overload tripping operation is performed is calculated and can be made available to the i&c system. after an overload tripping operation, the remaining cooling time can be displayed (characteristic curves for 2-pole and 3-pole loading in simocode pro system manual). phase failure/unbalance protection the level of the phase unbalance can be monitored and trans- mitted to the i&c system. if a specified limit value is violated, a defined and delayable response can be initiated. if the phase unbalance is larger than 50 %, the tripping time is also automatically reduced according to the overload characteris- tic since the heat generation of the motors increases in unbal- anced conditions. stall protection if the motor current rises above an adjustable blocking threshold (current threshold), a defined and delayable response can be configured for simocode pro. in this case, for example, the motor can be shut down independent of the overload protection. the blocking protection is only enabled after the configured class time has elapsed and avoids unnecessarily high thermal and mechanical loads as well as wear of the motor. thermistor motor protection this protection function is based on direct temperature measurements by means of temperature sensors in the stator windings or in the enclosure of the motor. these protective functions should be used, in particular, in motors with high operating frequencies, heavy-duty starting, intermittent and/or braking operation, but also in the case of speeds lower than the rated speed. simocode pro supports connection and evaluation of several ptc sensors connected in series on the basic unit. in addition, the sensor measuring circuit can be monitored for short-circuits and wire breakages. if the temperature of the motor increases beyond a defined limit or if there is a fault in the sensor measuring circuit, a defined response can be configured. ground-fault monitoring (internally) with a current measuring module or current/voltage measuring module simocode pro acquires and monitors all three phase currents. with vector addition of the phase currents, the motor feeder can be monitored for possible fault currents or ground faults with the help of internal calculations. internal earth fault monitoring is only available for motors with three-phase connections in directly grounded networks or in networks grounded with low impedance. the response of simocode pro when a ground fault is detected can be parameterized and delayed as required. ground-fault monitoring (external) with summation current transformer 1)2) external ground-fault monitoring is normally implemented for networks that are grounded with high impedance. using an additional summation current transformer (3ul2 20.-.a), even extremely low ground-fault currents can be measured. the response of simocode pro when a ground fault is detected can be parameterized and delayed as required. fault current measurement is performed for each summation current transformer for the following fault currents: 0.3/0.5/1 a monitoring of adjustable limit values for the motor current current limit value monitoring is used for process monitoring independent of overload protection. violation of a current limit value below the overload threshold can be an indication for a dirty filter in a pump or for an increasingly sluggish motor bearing, for example. violation of the lower current limit value can be a first indication of a worn drive belt. simocode pro supports two-step monitoring of the motor current for freely selectable upper and lower current limit values. the response of simocode pro can be freely configured and delayed if it reaches an alarm or tripping threshold. voltage monitoring 3) by measuring the voltage directly at the circuit-breaker or at the fuses in the main circuit, even when the motor is deactivated, simocode pro can also obtain information about the reclosing capability of the feeder and signal it if required. simocode pro supports two-stage undervoltage monitoring for freely selectable limit values. the response of simocode pro can be freely configured and delayed if it reaches an alarm or tripping threshold. monitoring the active power 3) the active power characteristic of a motor provides an accurate statement of the actual loading over the complete range. excessive loading will cause increased wear in the motor and can result in early failure. insufficient active power can be an indication of, for example, motor idling. simocode pro supports two-step monitoring of the active power for freely selectable upper and lower current limit values. the response of simocode pro can be freely configured and delayed if it reaches an alarm or tripping threshold. monitoring the power factor 3) especially in the low-end performance range of a motor, the power factor varies more than the motor current or active power. monitoring of the power factor is therefore particularly useful for distinguishing between motor idling and fault events such as a tear in a drive belt or a crack in a drive shaft. simocode pro supports two-stage monitoring of power factor undershoot for freely selectable limit values. the response of simocode pro can be freely configured and delayed if it reaches an alarm or tripping threshold. temperature monitoring 1)4) the temperature can be monitored, for example, in the motor windings or at the bearings through up to three resistance sensors connected to the temperature module. simocode pro supports two-stage monitoring of overheating for freely selectable limit values. the response of simocode pro can be freely configured and delayed if it reaches an alarm or

also with direction reversal 1) two speeds, motors with separate dahlander windings (also with direction reversal) 1) slide control 1) solenoid valve actuation 1) actuation of a circuit-breaker (mccb) actuation of a 3rw soft starter also with direction reversal 1) these control programs already include all the software interlocks and logic operations required for operation of the required motor functions. it is also monitored whether the current checkback of the motor feeder corresponds with the control command. if not, simocode pro opens the motor contactor and generates an alarm indication. depending on the application, motor control can be switched over or carried out simultaneously from several control stations, e.g.: from the i&c system through profibus dp from a pc/pg through profibus dp from the control cabinet door through the operator panel from a pc/pg on the system interface through simocode pro from a local control station on the motor. in this case, the buttons, switches and indicator lights are connected to the inputs and outputs of simocode pro. regardless of whether a control command is sent to simocode pro via profibus dp using the operator module or via the buttons connected to the binary simocode pro inputs, simocode pro can execute these control commands simultaneously or in accordance with the enabled commands defined during configuration. these predefined control functions can also be flexibly adapted to each customized configuration of a motor feeder by means of freely configurable logic modules (truth tables, counters, timers, edge evaluation etc.). in addition, special standard functions are stored in simocode pro which can also be used to extend the protection and control functions, e.g.: power failure monitoring 1) for automatic, time-staggered restart of motors following a network failure e.g. with the help of a separate voltage relay (voltage controller). fault signaling modules for external faults with or without manual or automatic acknowledgement for generating internal messages or for tripping simocode pro in response to freely definable events (e.g. overspeed monitor has been activated). designations/names can also be assigned to the external faults which are stored in the device and which are therefore also available to the i&c system. emergency start function and reset of the thermal memory of simocode pro after tripping, i.e. immediate restart is possible (important, for example, for pumps used to extinguish fires). test function for the load feeder circuit when the main control switch is open to test the control circuit while the main circuit is de-energized. detailed operational, service and diagnostics data simocode pro provides a variety of operating, service and diagnostic data, such as: operating data the switching state of the motor (on, off, clockwise, counter- clockwise, fast, slow) is derived from the current flow in the main circuit, so checkbacks are not required through auxiliary contacts from circuit-breakers and contactors current in phase 1, 2, 3 and maximum current in % of the set current voltage in phases 1, 2, 3 in v 3) active power in w 3) apparent power inva 3) power factor in % 3) phase unbalance in % phase sequence 3) temperature in sensor circuits 1, 2, 3 and maximum temperature in c 1)4) current values of the analog signals 1)2) time until tripping in sec. temperature rise for motor model in % remaining cooling time of the motor in sec. etc. service data motor operating hours (can be reset) motor stop times (can be reset) number of motor star ts (can be reset) number of remaining permissible motor starts number of overload trips (can be reset) internal comments, stored in the device for each feeder, e.g. notes for maintenance events etc. 1) using basic unit 2. 2) an additional analog module is required. 3) using basic unit 2 with current/voltage measuring module. 4) an additional temperature module is required.

simocode 3uf motor management and control devices 7/27 siemens lv 1 t 2006 7 simocode-dp 3uf5 motor protection and control devices function protective and monitoring functions for the protection of loads against impermissible high temperature rises types of overload protection: current-sensitive, electronic overload protection with adjustable tripping characteristics (class times) simocode-dp protects three-phase or ac motors from overloading according to the requirements of iec 60947-4-1. the class (trip class) indicates the maximum tripping time during which simocode-dp must trip at 7.2 times the operational current from cold. the trip class can be set in six stages from class 5 to class 30. the break time can therefore be extremely finely adjusted to the load torque of the motor ? to optimize utilization of the motor (see also the section characteristic curves ). phase failure/unbalance monitoring a signal is output for a phase unbalance greater than 40 %. the tripping times of the overload characteristic are reduced, because the heat generated in the motor rises under unbalanced conditions (additional eddy-current losses). thermistor motor protection temperature-dependent motor protection is based on direct temperature measurements in the motor. these protective functions should be used, in particular, in motors with high operating frequencies, heavy-duty starting, intermittent and/or braking operation, but also in the case of a blocked air supply or speeds lower than the rated speed. for this reason, a wide range of different temperature sensors are available that are installed in the stator winding or in the motor enclosure. simocode-dp can evaluate the following sensor types: - binary ptc sensors whose resistance rises sharply when the temperature limit is reached - analog temperature sensors, such as ntc, kty83/84, which have an almost linear characteristic curve and can therefore be set to any warning or switch-off temperatures eex e type of protection the simocode-dp system is in compliance with the regulations for overload protection of explosion-protected motors of the eex e "increased safety" type of protection according to en 50019 en 60079-7, iec 60079-7 en 60079-14 (potentially explosive areas) en 50281 (areas with combustible dust) atex/ptb test regulations in the case of simocode-dp units with 24 v dc control infeed, isolation by battery or safety transformer according to en 61558-2-6 must be assured. ec type test certificate: ptb01 atex 3219 test report: ptb ex 01-30013 rotor locking protection when the motor current rises above a rotor locking threshold that can be set, simocode-dp does not trip according to the overload characteristic, but switches off immediately instead. the prevention of unnecessary thermal loads prevents premature aging of the motor. the rotor locking protection is not active for start-up monitoring until the class time has elapsed, e.g. for class 10 after 10 seconds. ground-fault monitoring two qualitatively different ground-fault monitoring functions are offered: "internal" ground-fault monitoring by means of calculation the internal ground-fault monitoring is only suitable for motors with 3-wire connection and for networks that are grounded directly or with a low impedance. in this case, the ground-fault current is calculated by vector addition of the phase currents of the simocode-dp current transformer. an additional summation current transformer is not necessary. in fault-free systems, the vectorial summation current of the three phases is zero; if this is not the case, a ground-fault is signaled. ground-fault currents that are more than 30 % of the operating current i e are detected. "internal" ground-fault monitoring by means of measurement the external ground-fault detection is normally used in supply systems that have a high impedance ground. an additional summation current transformer (3ul2 20.-.a) is required for this method that is also suitable for extremely low ground-fault currents. detected fault current, depending on the summation current transformer: 0.3/0.5/1 a. current limit monitoring i >, i < current limit monitoring is not used for motor protection, but for process monitoring. it is used to detect developing irregularities in the plant early, e.g. motor bearings becoming tight (consequence: upper limit responds) or the belt coupling to the drive machine tears (consequence: lower limit responds). comprehensive motor and plant diagnostics simocode-dp provides a variety of measuring, operating and diagnostics data concerning the load feeder: up-to-date information during operation , e.g.: - the currently flowing phase current in % - the switching state of the motor (on, off, clockwise, counterclockwise, fast, slow) derived from the current flow - manual/automatic mode -test mode - cooling time activated after an overload tripping operation detection of incipient faults , e.g.: - overload warning - current limit overshoot - phase unbalance - thermistor warning rapid diagnostics in the event of an alarm , e.g.: - overload - thermistor motor protection - rotor locking - current limit overshoot - checkback error (e.g. no current following on command) preventive maintenance by means of statistical data , e.g.: - number of starts - number of overload trips - tripping currents - operating hours integrated standard programs for motor control in simocode-dp, a number of different opportunities for controlling the motor has been predefined and can be called up in the form of control functions: overload relay direct-on-line starter reversing starter wye-delta starter

the om-simocode-dp object manager should, in this case, always be combined with the start-up and service software win-simocode-dp/professional both software packages must be installed on the pg/pc on which the hardware configuration of simatic s7 is performed. this ensures that win-simocode-dp/professional can be called up directly from hw-config. parameter sets created with win-simocode-dp/professional are loaded into the step 7 data storage by means of om and automatically transferred to simocode-dp during start-up. functions specific to simatic s7, such as diagnostic and hardware interrupts are supported, which means easier s7-wide configuration as well as optimal performance in the transfer of diagnostic data. function block fb-simocode for "totally integrated" in pcs7 with pcs7-fb simocode-dp it is easy and convenient to integrate simocode-dp into the simatic pcs 7 process control system. pcs7-fb simocode-dp contains the diagnostic and driver blocks corresponding with the diagnostic and driver concept of simatic pcs 7 as well as the elements (symbols and faceplate) required for operator control and process monitoring. the application is integrated by graphic interconnection using the cfc editor. the technological and signal processing functions of the pcs7-fb simocode-dp are based on the simatic pcs 7 standard libraries (driver blocks, technological blocks) and are optimally tailored to simocode- dp. users who previously configured motor feeder circuits using conventional technology by means of signal blocks and motor or valve blocks, can now easily switch to pcs7-fb simocode-dp. the pcs7-fb simocode-dp supplied on cd-rom allows the user to run the required engineering software on one engineering station (single license) including the runtime software for executing the as blocks in an automation system (single license).

7 monitoring relays 3ug monitoring relays for electr ical and additional measurements level monitoring 7/82 siemens lv 1 t 2006 overview the 3ug35 01 level monitoring relay is used together with the 2- or 3-pole sensors to monitor the levels of conductive liquids. function the principle of operation is based on measuring the electrical resistance of the liquid between two immersion sensors and a reference terminal. if the measured value is lower than the sensitivity set at the front, the output relay changes its switching state. in order to exclude electrolytic phenomena in the liquid, the sensors are supplied with alternating current. two-level control: the output relay changes its switching state as soon as the liquid level reaches the maximum sensor, while the minimum sensor is submerged. the relay returns to its original switching state as soon as the minimum sensor no longer has contact with the liquid. for safe resetting, the supply voltage must be interrupted for at least 0.5 s (t3). the delay times t1 and t2 of the output relay have not been included in the diagram in order to enhance clarity. note: it is also possible to connect other resistance sensors to the min and max terminals in the range 5 to 100 k , e.g. photoresistors, temperature sensors, encoders based on resistance etc. the monitoring relay can therefore also be used for other applications apart from monitoring the levels of liquids.

7 monitoring relays 3rn1 thermistor motor protection for ptc sensors 7/96 siemens lv 1 t 2006 overview thermistor motor protection devices are used for direct monitoring of the motor winding temperature. for this purpose, the motors are equipped with temperature-dependent resistors (ptc) that are directly installed in the motor winding and abruptly change their resistance at their limit temperature. design the 3rn1 tripping units are suitable for use in any climate and finger-safe according to en 0106 part 50274. they comply with: en 61000-6-2 and en 61000-6-4, "electromagnetic compatibility of i&c equipment in industrial process engineering" en 60947-8 the terminals of the auxiliary contacts are designated in accordance with en 50005. the 3rn1 tripping units are suitable for snap-on mounting onto 35 mm standard mounting rails according to en 50022 or for screw-mounting using an adapter (accessories). any mounting position is possible. for devices with the "manual reset" function, the test function can be activated and a trip simulated by pressing the blue test/reset button for longer than 2 seconds. if a type a temperature sensor is connected to a type a tripping unit, compliance with the operating temperatures is assured (on pick-up and reset) according to iec 60034-11-2 (en 60947-8). the characteristic curves of the type a temperature sensors are described in en 60947-8, din 44081 and din 44082. use in areas subject to explosion hazard for gases all devices are approved for equipment group ii, category (2) in area "g" (areas that contain explosive gases, vapor, spray and air mixtures). with ptb 01 atex 3218 ex ii (2) g, compliance with guideline 94/9 eg appendix ii is confirmed. the safety devices must be selected with suitable settings for the safe operation of motors of the "increased safety" (eex e) and "flameproof enclosure" (eex d) degrees of protection and are accessed outside the area subject to explosion hazard. ptb 01 atex 3218 ex ii (2) g the increased danger in areas subject to explosion hazard demands careful analysis of the operator's guide, the safety and commissioning instructions and the standard (en 60079-14/ vde 0165) for electronic equipment in areas subject to gas explosion hazards. a risk analysis must be performed for the complete plant or machine. if this risk analysis results in a minimal potential for danger (safety category 1), all 3rn1 tms tripping units can be implemented taking into account the safety notes. in the case of plants or machines with a high potential risk, variants with integrated short-circuit detection in the sensor circuit are necessary. use in areas subject to explosion hazard for dust ptb 01 atex 3218 ex ii (2) g 3rn10 11-.b/-.g, 3rn10 12-.b/-.g and 3rn10 13-...0 tripping units can be used as safety devices for motors in areas subject to gas explosion hazard for protection against impermissible overheating due to overload. if the atex marking has the extension "d:=dust", these units can also be used as protective devices for motors in areas subject to dust explosion hazard (en 50281-1-1). additional information is provided in the eu type test certificate which can be obtained from the internet. the units comply with the requirements of the following classes: the measuring circuit leads must be routed as separate control leads. it is not permitted to use cores from the supply line of the motor or any other main supply cables. if extreme inductive or capacitive interference is expected as a result of power lines routed in parallel, shielded control leads must be used. 4000 1330 550 250 20 -20c 0 tnf-20 tnf-5 tnf tnf+15 t r nsb00320 tnf+5 device class 3rn10 00, 3rn10 10, 3rn10 11-.c, 3rn10 12-.c, 3rn10 22, 3rn10 62 en 954-1: category 1 3rn10 11-.b, 3rn10 11-.g, 3rn10 12-.b, 3rn10 12-.g, 3rn10 13 en 954-1: category 2

for mounting, use installation manual no.: 3zx1012-0rn10-1aa1. the 3rn10 is not intended for installation in hazardous areas. for installation in areas subject to explosion hazards, the 3rn10 must be enclosed in a flameproof casing. for tripping units with a 24 v ac/dc control voltage, electrical isolation must be secured with a battery network or a safety transformer according to din vde 0551. when tripping units with auto-reset function are used, a reset is performed automatically after the cooling time has expired. it must be ensured by means of an external interlock (latching with a separate on and off button) that the machine to be monitored does not start up again spontaneously. units with the auto-reset function must not be used in applications in which the unexpected restart can lead to personal injury or property damage. in the case of tripping units without short-circuit detection, during commissioning or after modifications or maintenance work (assembly, disassembly) on the equipment, the sensor resistance must be measured using a suitable measuring instrument. for resistances < 50 ohm, the sensor circuit must be checked for a short-circuit. if 3rn10 00 units are used to protect eex e motors, separate monitoring of the control voltage is recommended because there is no ready led to indicate connection to the supply voltage. if 3rn10 13-.bw01 units are used to protect eex e motors, separate monitoring of the control voltage is recommended because the switching status of the auxiliary contacts does not change if the control voltage fails (use of a bistable relay is recommended). before commissioning, the effectiveness of the protection function must be checked. function the 3rn1 tripping units operate in accordance with the closed- circuit principle and therefore monitor themselves for open- circuit (except: warning output in the case of 3rn10 22). a momentary power failure of less than 50 ms does not change the status of the auxiliary contacts. the 3rn10 11, 3rn10 12 and 3rn10 13 units with 2 changeover contacts are also equipped with short-circuit detection in the sensor circuit. the unit will trip in the event of a short-circuit in the sensor circuit (resistance in sensor circuit < 20 ). all tripping units (except for 24 v ac/dc ) feature electrical isolation between the control circuit and the sensor circuit. 3rn10 00 compact tripping units the compact tripping unit is equipped with a red led (tripped) for the tripped display and a changeover contact. after the unit has tripped, it is automatically reset once the thermistors have cooled down. the root of the changeover contact is connected to the control voltage (95 is connected to terminal a1). this unit is particularly suitable in circuits in which the control circuit and signaling circuit have the same potential, e.g. in local control boxes. 3rn10 10, 3rn10 11, 3rn10 12, 3rn10 13 standard tripping units the standard units are equipped with two leds (ready and tripped) for an operating and tripped display and are available with either 1 no + 1 nc or with 2 co contacts. they are available depending on the version with automatic reset (3rn10 10), manual/remote reset (3rn10 11) or manual/automatic and remote reset (3rn10 12 and 3rn10 13). remote reset can be achieved by connecting an external pushbutton with a normally-open function to terminals y1 and y2. if terminals y1 and y2 are bridged, tripping will be followed by an automatic reset. the 3rn10 11, 3rn10 12 and 3rn10 13 units with 2 cos also have short-circuit monitoring in the sensor circuit. the 3rn10 12 and the 3rn10 13 are non-volatile. this means that even if the control voltage fails, a preceding trip will be latched. in the case of the 3rn10 13 tripping unit, tripping due to a short- circuit in the sensor circuit will be indicated by a flashing red led. the monostable version also indicates open-circuit in the sensor circuit by flashing of the red led. 3rn10 22 "warning and disconnection" tripping units two sensor circuits can be connected to one 3rn10 22 tripping unit that acts on one output relay with 1 no contact for warning and 1 co for disconnection. temperature sensors with different rated response temperatures tnf are used to implement the "warning" and "disconnection" functions. when the "warning" sensor circuit responds, a yellow led is lit and when the "disconnection" circuit responds, a red led is lit. the sensor circuits have a different reset response and operating behavior: "warning" (terminals 2t1, t2) only features automatic reset and uses the open-circuit principle. "disconnection" (terminals 1t1, t2) can be changed from manual reset to automatic reset by linking terminals y1 and y2. remote reset is implemented by connecting an external pushbutton with a normally-open function. conductor cross- section in mm 2 cable length in m for tripping units without short-circuit detection 3rn10 00, 3rn10 10 3rn10 11-.c 3rn10 12-.c 3rn10 22, 3rn10 62 with short-circuit detection 1) 3rn10 11-.b/-.g 3rn10 12-.b/-.g 3rn10 13 2.5 2 x 2800 2 x 250 1.5 2 x 1500 2 x 150 0.5 2 x 500 2 x 50

7 interface converters 3rs17 interface converters 7/112 siemens lv 1 t 2006 overview interface converters perform the coupling function for analog signals on both the input side and the output side. they are indispensable when processing analog values with electronic controls. under harsh industrial conditions in particular, it is often necessary to transmit analog signals over long distances. this means that electrical isolation is essential due to the different supply systems. the resistance of the wiring causes potential differences and losses which must be prevented. electromagnetic disturbance and overvoltages can affect the signals on the input side in particular or even destroy the analog modules. all terminals of the 3rs17 interface converters are safe up to a voltage of 30 v dc and protected against switching poles. short-circuit protection is an especially important function for the outputs. the devices are emc-tested according to en 50081 (basic technical standard for emitted interference) en 61000-6-2 (basic technical standard for immunity to interference) the analog signals comply with iec 60381-1/2 function active interface converters active interface converters provide maximum flexibility for the application by the use of an external supply voltage. configuration with active interface converters is extremely easy because input and output resistances and voltage drops are compensated by the auxiliary supply. they support complete voltage isolation as well as conversion from one signal type to another or reinforcement. the load of the measured value transmitter is negligible. passive interface converters passive interface converters do not require an external supply voltage. this advantage can only be used by current signals that are converted 1:1. reinforcement or conversion is not possible. the converters are used for complete electrical isolation of current signals and to protect the inputs and outputs. passive isolators do not operate reaction-free, any load on the output produces an equal load on the input. when the passive converter is to be used, the output performance of the sensor and the input resistance of the analog input must be analyzed. this technique is being increasingly implemented in the case of pure current signals. calculation guide for passive converters note: please note the following when using passive isolators: the current-driving voltage of the measuring transducer u e must be sufficient to drive the maximum current of 20 ma over the passive isolator with a voltage loss of u v = 2.7 v and the load r b . this means that: u b u e =2.7v+20ma r b distribution of the voltages in the case of passive isolators input voltage depending on the load at i a =20ma the following diagram shows the input voltage u e as a function of the load r b taking into account the voltage loss u v . if the load is known, the y-axis shows the minimum voltage that has to be supplied by the current source in order to drive the maximum current of 20 ma over the passive isolator and load. current carrying capacity of the outputs a maximum output resistance is specified for current signals. this resistance value specifies how large the input resistance of the next device connected in series can be as a result of the power of the converter. for voltage signals, the maximum current that can be drawn from the output is the decisive factor. 2-way isolation in the case of 2-way isolation, the input is galvanically isolated from the output. the "null potential" of the supply voltage is the same as the reference potential for the analog output signal. 3-way isolation for the 3-path isolation, each circuit is electrically isolated from the other circuits, i.e. input, output, and supply voltage do not have a potential connection.
