solid state relays technical information 829 precautions and notes on correct use !warning do not touch the ssr terminal section (charged section) when the power supply is on. for ssrs with terminal covers, be sure to at- tach the cover before use. touching the charged section may cause electric shock. do not touch the ssr or the heat sink either while the power sup- ply is on, or immediately after the power is turned off. the ssr/ heat sink will be hot and will cause burns. do not touch the ssr load terminal immediately after the power is turned off. the internal snubber circuit is charged and may cause electric shock. ? do not apply excessive voltage or current to the ssr input or out- put circuits, or ssr malfunction or fire damage may result. do not operate if the screws on the output terminal are loose, or heat generated by a terminal error may result in fire damage. do not obstruct the air flow to the ssr or heat sink, or heat gener- ated from an ssr error may cause the output element to short, or cause fire damage. be sure to conduct wiring with the power supply turned off, or electric shock may result. follow the correct use section when conducting wiring and solder- ing. if the product is used before wiring or soldering are complete, heat generated from a power supply error may cause fire damage. when installing the ssr directly into a control panel so that the panel can be used as a heat sink, use a panel material with low thermal resistance such as aluminum or steel. if a material with high thermal resistance such as wood is used, heat generated by the ssr may cause fire or burning. before using the ssr unexpected events may occur before the ssr is used. for this rea- son it is important to test the ssr in all possible environments. for example, the features of the ssr will vary according to the product being used. all rated performance values listed in this catalog, unless otherwise stated, are all under the jis c5442 standard test environment (15 to 30 c, 25% to 85% relative humidity, and 86 to 106 kpa atmosphere). when checking these values on the actual devices, it is important to ensure that not only the load conditions, but also the operating envi- ronmental conditions are adhered to. zero cross function an ssr with a zero cross function operates when the ac load volt- age approaches the zero point or its vicinity, and releases when the current reaches the zero point. an ssr with a zero cross function reduces clicking noises that may be generated when the load is turned on. life expectancy (mttf) the mean time to failure (mttf) of ssrs is 100,000 hours, which varies with the operating conditions. to ensure long life and stable operation, take proper countermeasures against extremely high or low operating temperature, heavy fluctuations of ambient tempera- ture, and/or long continuous energization. input circuit input noise ssrs need only a small amount of power to operate. this is why the input terminals must shut out electrical noise as much as possible. noise applied to the input terminals may result in malfunction. the following describes measures to be taken against pulse noise and inductive noise. pulse noise a combination of capacitor and resistor can absorb pulse noise effectively. the following is an example of a noise absorption circuit with capacitor c and resistor r connected to an ssr incorporating a photocoupler. the value of r and c must be decided carefully. the value of r must not be too large or the supply voltage (e) will not be able to satisfy the required input voltage value. the larger the value of c is, the longer the release time will be, due to the time required for c to discharge electricity. note: for low-voltage models, sufficient voltage may not be applied to the ssr because of the relationship between c, r, and the in- ternal impedance. when deciding on a value for r, check the input impedance for the ssr. output (load voltage) input on off r c pulse width pulse voltage pulse voltage (v) pulse width ( s)
830 solid state relays technical information inductive noise do not wire power lines alongside the input lines. inductive noise may cause the ssr to malfunction. if inductive noise is imposed on the input terminals of the ssr, use the following cables according to the type of inductive noise, and reduce the noise level to less than the must release voltage of the ssr. twisted-pair wire: for electromagnetic noise shielded cable: for static noise a filter consisting of a combination of capacitor and resistor will effec- tively reduce noise generated from high-frequency equipment. note: r: 20 to 100 ? c: 0.01 to 1 f input conditions input voltage ripples when there is a ripple in the input voltage, set the input voltage so that the peak voltage is lower than the maximum operating voltage and the root voltage is above the minimum operating voltage. countermeasures for leakage current when the ssr is powered by transistor output, the must release volt- age may be insufficient due to leakage current while power is off. to counteract this, connect bleeder resistance as shown in the dia- gram below and set the bleeder resistance so that vr is 0.5 v or less. on/off frequency the on/off frequency should be set to 10 hz maximum for ac load switching and 100 hz maximum for dc load switching. if switching occurs at frequencies exceeding these values, the ssr output will not be able to follow-up. input impedance in ssrs which have wide input voltages (such as g3f and g3h), the input impedance varies according to the input voltage and changes in the input current. for semiconductor-driven ssrs, changes in volt- age can cause malfunction of the semiconductor, so be sure to check the actual device before usage. see the following examples. applicable input impedance for a photocoupler- type ssr without indicators (example) g3f, g3h (without indicators) applicable input impedance for a photocoupler- type ssr with indicators (example) g3b, g3f, g3h (with indicators) applicable input impedance (example) g3cn filter high-frequency device load 0 v peak voltage root voltage bleeder resistance input current (ma) input impedance (k ? ) input voltage (v) input current input impedance input current (ma) input voltage (v) input impedance (k ? ) input current input impedance input voltage (v) input current (ma) input impedance (k ? ) input current input impedance
solid state relays technical information 831 output circuit ac on/off ssr output noise surges if there is a large voltage surge in the ac current being used by the ssr, the c/r snubber circuit built into the ssr between the ssr load terminals will not be sufficient to suppress the surge, and the ssr transient peak element voltage will be exceeded, causing over- voltage damage to the ssr. only the following models have a built-in surge absorbing varistor: g3na, g3s, g3pa, g3ne, g3nh, g3dz (some models), g3rz, and g3fm. when switching an inductive load with any other models, be sure to take countermeasures against surge, such as adding a surge absorbing element. in the following example, a surge voltage absorbing element has been added. select an element which meets the conditions in the following table as the surge absorbing element. dc on/off ssr output noise surges when an l load, such as a solenoid or electromagnetic valve, is con- nected, connect a diode that prevents counter-electromotive force. if the counter-electromotive force exceeds the withstand voltage of the ssr output element, it could result in damage to the ssr output ele- ment. to prevent this, insert the element parallel to the load, as shown in the following diagram and table. as an absorption element, the diode is the most effective at sup- pressing the counter-electromotive force. the release time for the solenoid or electromagnetic valve will, however, increase. be sure to check the circuit before use. to shorten the time, connect a zener diode and a regular diode in series. the release time will be short- ened at the same rate that the zener voltage (vz) of the zener diode is increased.

832 solid state relays technical information forward and reverse operation of single-phase inductive motors note: 1. the voltage between the load terminals of either ssr 1 or ssr 2 when turned off is approximately twice as high as the supply voltage due to lc coupling. be sure to use an ssr model with a rated output voltage of at least twice the supply voltage. for example, if the motor operates at a sup- ply voltage of 100 vac, the ssr must have an output volt- age of 200 vac or higher. 2. make sure that there is a time lag of 30 ms or more to switch over sw1 and sw2. on/off control of three-phase inductive motors forward and reverse operation of three-phase inductive motors make sure that signals input into the individual ssrs are proper if the ssrs are applied to the forward and reverse operation of a three- phase motor. if sw1 and sw2 as shown in the following circuit dia- gram are switched over simultaneously, a phase short-circuit will result on the load side, which may damage the output elements of the ssrs. this is because the ssr has a triac as an output element that is turned on until the load current becomes zero regardless of the absence of input signals into the ssr. therefore, make sure that there is a time lag of 30 ms or more to switch over sw1 and sw2. the ssr may be damaged due to phase short-circuiting if the ssr malfunctions with noise in the input circuit of a ssr. to protect the ssr from phase short-circuiting damage, a protective resistance r may be inserted into the circuit. the value of the protective resistance r must be determined accord- ing to the withstanding inrush current of the ssr. for example, the g3na-220b withstands an inrush current of 220 a. the value of the protective resistance r is obtained from the following. r > 220 v x 2 /200a = 1.4 ? considering the circuit current and weld time, insert the protective resistance into the side that reduces the current consumption. obtain the consumption power of the resistance from the following. p = i 2 r x safety factor (i = load current, r = protective resistance, safety factor = 3 to 5) selecting an ssr for different loads the following provides examples of the inrush currents for different loads. motor load po wer supp ly l c motor three- phase power supply input signal source r s t ac load and inrush current load inrush current/ normal current approx. 10 times approx. 10 to 15 times approx. 5 to 10 times approx. 2 to 3 times approx. 20 to 50 times 1 wave- form solenoid incan- descent lamp motor relay capacitor resis- tive load inrush current normal current
solid state relays technical information 833 heater load (resistive load) a resistive load has no inrush current. the ssr is generally used together with a voltage-output temperature controller for heater on/ off switching. when using an ssr with the zero cross function, most generated noise is suppressed. this type of load does not, however, include all-metal and ceramic heaters. since the resistance values at normal temperatures of all-metal and ceramic heaters are low, an overcurrent will occur in the ssr, causing damage. for switching of all-metal and ceramic heaters, select a power controller (g3px, consult your omron representative) with a long soft-start time, or a constant-current switch. lamp load a large inrush current flows through incandescent lamps, halogen lamps, and similar devices (approx. 10 to 15 times higher than the rated current). select an ssr so that the peak value of inrush current does not exceed half the inrush current resistance of the ssr. refer to ? repetitive ? (indicated by the dashed line) shown in the following figure. when a repetitive inrush current of greater than half the inrush current resistance is applied, the output element of the ssr may be damaged. motor load when a motor is started, an inrush current of 5 to 10 times the rated current flows and the inrush current flows for a longer time than for a lamp or transformer. in addition to measuring the startup time of the motor or the inrush current during use, ensure that the peak value of the inrush current is less than half the inrush current resistance when selecting an ssr. the ssr may be damaged by counter-electromo- tive force from the motor. be sure to install overcurrent protection for when the ssr is turned off. transformer load when the ssr is switched on, an energizing current of 10 to 20 times the rated current flows through the ssr for 10 to 500 ms. if there is no load in the secondary circuit, the energizing current will reach the maximum value. select an ssr so that the energizing cur- rent does not exceed half the inrush current resistance of the ssr. half-wave rectifying circuit ac electromagnetic counters and solenoids have built-in diodes, which act as half-wave rectifiers. for these types of loads, a half- wave ac voltage does not reach the ssr output. for ssrs with the zero cross function, this can cause them not to turn on. two meth- ods for counteracting this problem are described below. connect a bleeder resistance with approximately 20% of the ssr load current. use ssrs without the zero cross function. full-wave rectified loads ac electromagnetic counters and solenoids have built-in diodes, which act as full-wave rectifiers. the load current for these types of loads has a rectangular wave pattern, as shown in the following dia- gram. accordingly, ac ssrs use a triac (which turns off the element only when the circuit current is 0 a) in the output element. if the load cur- rent waveform is rectangular, it will result in an ssr reset error. when switching on and off a load whose waves are all rectified, use a -v model or power mos fet relay. -v-model ssrs: g3f-203sl-v, g3h-203sl-v power mos fet relay: g3dz, g3rz, g3fm heater load temperature controller (voltage output) non-repetitive repetitive energized time (ms) inrush current (a. peak) bleeder resistance load load circuit current wave pattern
834 solid state relays technical information small-capacity loads even when there is no input signal to the ssr, there is a small leak- age current (i l ) from the ssr output (load). if this leakage current is larger than the load release current, the ssr may fail to reset. connect a bleeder resistance r in parallel to increase the ssr switching current. load (e.g., relays) release voltage load (e.g., relays) release current inverter load do not use an inverter-controlled power supply as the load power supply for the ssr. inverter-controlled waveforms become rectangu- lar, so the dv/dt ratio is extremely large and the ssr may fail to reset. an inverter-controlled power supply may be used on the input side provided the effective voltage is within the normal operating volt- age range of the ssr. capacitive load the supply voltage plus the charge voltage of the capacitor is applied to both ends of the ssr when it is off. therefore, use an ssr model with an input voltage rating twice the size of the supply volt- age. limit the charge current of the capacitor to less than half the peak inrush current value allowed for the ssr. load power supply rectified currents if a dc load power supply is used for full-wave or half-wave rectified ac currents, make sure that the peak load current does not exceed the maximum usage load power supply of the ssr. otherwise, over- voltage will cause damage to the output element of the ssr. operating frequency for ac load power supply the operating frequency range for an ac load power supply is 47 to 63 hz. low ac voltage loads if the load power supply is used under a voltage below the minimum operating load voltage of the ssr, the loss time of the voltage applied to the load will become longer than that of the ssr operating voltage range. see the following load example. (the loss time is a < b.) before operating the ssr, make sure that this loss time will not cause problems. if the load voltage falls below the trigger voltage, the ssr will not turn on, so be sure to set the load voltage to 24 vac minimum. (except for the g3pa-vd and g3na-2 @@ b.) operation leakage current a leakage current flows through a snubber circuit in the ssr even when there is no power input. therefore, always turn off the power to the input or load and check that it is safe before replacing or wiring the ssr. r < e i l -i bleeder resistance r load e: load (e.g., relays) reset voltage i: load (e.g., relays) reset current load power supply bleeder resistance standards: 100-vac power supply, 5 to 10 k ? , 3 w 200-vac power supply, 5 to 10 k ? , 15 w voltage increase ratio ? v/ ? t = dv/dt: voltage increase ratio the dv/dt ratio tends to infinity, so the ssr will not turn off. peak voltage ssr operating voltage maximum value 100 vac (r load) trigger voltage trigger voltage trigger voltage trigger voltage trigger voltage 24 vac (r load) trigger voltage switch element snubber circuit input circuit trigger circuit varistor leakage current
solid state relays technical information 835 safety considerations error mode the ssr is an optimum relay for high-frequency switching and high- speed switching, but misuse or mishandling of the ssr may damage the elements and cause other problems. the ssr consists of semi- conductor elements, and will break down if these elements are dam- aged by surge voltage or overcurrent. most faults associated with the elements are short-circuit malfunctions, whereby the load cannot be turned off. therefore, to provide a safety feature for a control circuit using an ssr, design a circuit in which a contactor or circuit breaker on the load power supply side will turn off the load when the ssr causes an error. do not design a circuit that turns off the load power supply only with the ssr. for example, if the ssr causes a half-wave error in a circuit in which an ac motor is connected as a load, dc energiz- ing may cause overcurrent to flow through the motor, thus burning the motor. to prevent this from occurring, design a circuit in which a circuit breaker stops overcurrent to the motor. ssr mounting panel quality if g3na or g3ne ssrs are to be mounted directly onto the control panel, without the use of a heat sink, be sure to use a panel material with low thermal resistance, such as aluminum or steel. do not mount the ssr on a panel with high thermal resistance, such as a panel coated with paint. doing so will decrease the radiation effi- ciency of the ssr, causing heat damage to the ssr output element. do not mount the ssr on a panel made of wood or any other flam- mable material. otherwise the heat generated by the ssr will cause the wood to carbonize, and may cause a fire. overcurrent protection a short-circuit current or an overcurrent flowing through the load of the ssr will damage the output element of the ssr. connect a quick-break fuse in series with the load as a short-circuit protection measure. design a circuit so that the protection coordination conditions for the quick-break fuse satisfy the relationship between the ssr surge resistance (i s ), quick-break fuse current-limiting feature (i f ), and the load inrush current (i l ), shown in the following chart. operation indicator the operation indicator turns on when current flows through the input circuit. it does not indicate that the output element is on. ssr life expectancy the ssr is not subject to mechanical wear. therefore, the endur- ance of the ssr depends on the rate of internal component malfunc- tion. for example, the rate for the g3m-202p is 321 fit (1 fit = 10 ? 9 = (malfunctions/operation)). the mttf calculated from this value is as follows: mttf = 321/ 60 = 3.12 10 6 (operations) the effects of heat on the solder also need to be considered in esti- mating the total life expectancy of the ssr. the solder deteriorates due to heat-stress from a number of causes. omron estimates that the ssr begins to malfunction due to solder deterioration approxi- mately 10 years after it is first installed. operation and storage environment precautions operation and storage locations do not operate or store the relay in locations subject to direct sun- light or ultraviolet rays. otherwise the resin will deteriorate, thereby causing cracks and other damage to the case. do not operate or store the relay in locations subject to exposure to water or chemi- cals. otherwise rust, corrosion, and deterioration of the resin will occur. extended storage of ssr if the ssr is stored for an extended period of time, the terminals will be exposed to the air, reducing its solderability due to such effects as oxidation. therefore, when installing a relay onto a board after a long time in storage, check the state of the solder before use. also, take preventive measures so that the terminals will not be exposed to water, oil, or solvents while they are stored. vibration and shock do not subject the ssr to excessive vibration or shock. otherwise the ssr will malfunction and may cause damage to the internal com- ponents. to prevent the ssr from abnormal vibration, do not install the ssr in locations or by means that will subject it to vibration from other devices, such as motors. solvents do not allow the ssr to come in contact with solvents such as thin- ners or gasoline. doing so will dissolve the markings on the ssr. oil do not allow the ssr terminal cover to come in contact with oil. doing so will cause the cover to crack and become cloudy. location cause result input area overvoltage input element damage output area overvoltage output element damage overcurrent whole unit ambient temperature exceeding maximum output element damage poor heat radiation time (unit: s) peak current (a) input terminal input circuit input indicator output circuit output terminal
836 solid state relays technical information pcb ssr soldering ssrs must be soldered at 260 c within five seconds. for models, however, that conform to separate conditions, perform soldering according to the specified requirements. use a rosin-based non-corrosive flux that is compatible with the material of the ssr. ultrasonic cleaning do not perform ultrasonic cleaning. performing ultrasonic cleaning after the ssr base has been installed will cause ultrasonic waves to resonate throughout the ssr internal structure, thereby damaging the internal components. handling the ssrs do not drop the ssr is a high-precision component. do not drop the ssr or subject it to excessive vibration or shock regardless of whether the ssr is mounted or not. the maximum vibration and shock that an ssr can withstand varies with the model. refer to the relevant datasheet. the ssr cannot maintain its full performance capability if the ssr is dropped or subjected to excessive vibration or shock resulting in pos- sible damage to its internal components. the impact of shock applied to the ssr that is dropped varies, and depends on the floor material, the angle of collision with the floor, and the dropping height. for example, if a single ssr is dropped on a plastic tile from a height of 10 cm, the ssr may receive a shock of 1,000 m/s 2 or more. handle ssrs in in-line packages with the same care and keep them free from excessive vibration or shock. pcb-mounting ssrs suitable pcbs pcb material pcbs are classified into epoxy pcbs and phenol pcbs. the following table lists the characteristics of these pcbs. select one, t aking into account the application and cost. epoxy pcbs are recommended for ssr mounting in order to prevent the solder from cracking. pcb thickness the pcb may warp due to the size, mounting method, or ambient operating temperature of the pcb or the weight of components mounted to the pcb. should warping occur, the internal mechanism of the ssr on the pcb will be deformed and the ssr may not pro- vide its full capability. determine the thickness of the pcb by taking the material of the pcb into consideration. terminal hole and land diameters refer to the following table to select the terminal hole and land diam- eters based on the ssr mounting dimensions. the land diameter may be smaller if the land is processed with through-hole plating. mounting space the ambient temperature around the sections where the ssr is mounted must be within the permissible ambient operating tempera- ture. if two or more ssrs are mounted closely together, the ssrs may radiate excessive heat. therefore, make sure that the ssrs are separated from one another at the specified distance provided in the datasheet. if there is no such specification, maintain a space that is as wide as a single ssr. provide adequate ventilation to the ssrs as shown in the following diagram. item epoxy phenol glass epoxy paper epoxy paper phenol electrical characteristics high insulation resistance. highly resistive to moisture ab- sorption. inferior to glass epoxy but superior to paper phenol pcbs. new pcbs are highly insulation-resistive but easily affected by moisture absorption and cannot maintain good insulation performance over a long time. mechanical characteristics the dimensions are not easily af- fected by temperature or humidity. ideal for through-hole or multi-lay- er pcbs. inferior to glass epoxy but superior to paper phenol pcbs. the dimensions are easily affected by temperature or humidity. not suitable for through-hole pcbs. economical efficiency expensive rather expensive inexpensive application applications that require high reli- ability. applications that may require less reliability than those for glass epoxy pcbs but require more reliability than those of paper phenol pcbs. applications in comparatively good environments with low-density wiring. hole dia.
