2686_en_d automation fl switch sfn?24vac data sheet ? phoenix contact 2009-12 1description the fl switch sfn?-24vac range of factory line switches can be used for quic k and cost-effective ethernet network expansion to the field level. due to the narrow housing design, the switches ar e suitable for use in control cabinets and junction boxes. the fl switch sfn?-24vac switches support the auto negotiation function on the rj45 ports and offer transmission speeds of 10/1 00 mbps. mixed operation for the connection of segments with different data transmission speeds is also supported. the rj45 ports offer an auto crossing function, which means it is not necessary to make a distinction between 1:1 and crossover cables. unused rj45 ports can be fitted with security caps to provide mechanical protection ag ainst unauthorized use. 2 features and benefits ? switched ethernet networks reduce traffic and non- predictable timing ? pretagged high priority messages are forwarded before lower priority messages during periods of high network traffic ? auto-negotiation and autocross simplify cabling ? couple copper network segments with different bit rates with automatic detection of the data transmission speed of 10 or 100 mbps ? individual leds at each po rt indicate communication activity and data rate ? -0 to 60c operating range ? removable power connector ? ns 35 din rail (en 60715) compatible ? industrial rated, rugged me tal housing for industrial applications ? low-cost, low-complexity security by connecting layer 1 security elements at the rj45 ports to restrict access and tamper ing (optional) ? meets iec 61000-6-2 electrical noise immunity ? meets iec 60068-2-6 vibration test standards ? meets iec 60068-2-27 shock test standards make sure you always use the latest documentation. it can be downloaded at www.phoenixcontact.net/catalog . this data sheet is valid for all pr oducts listed on the following page: five- and eight-port standard function ethernet switch with narrow housings for 24 v ac power

fl switch sfn?24vac 2686_en_d phoenix contact 5 6.3 power connection the switch is designed for selv and pelv operation at 24 v ac/dc according to iec 61140/en 61140. only selv and pelv according to the de fined standards may be used for supply purposes. snapping the switch onto a grounded mounting rail connects it to the ground potential. in an environment particularly prone to emi, nois e immunity can be increased by an additional low-impeda nce connection to functional earth ground (see figure 2). figure 2 power connections use power conductors between 0.2 - 2.5 mm2 (24 - 12 awg). torque connecti on screws to 0.5 - 0.6 nm (5 - 7 lb-in.). 6.4 ethernet interface the fl switch sfn?24vac has five/eight ethernet ports on the front in rj45 format to which only twisted-pair cables with an impedance of 100 can be connected. the data transmission speed is 10/100 mb ps. in addition, every port has an auto crossing function: it is not necessary to make a distinction between 1:1 or crossover ethernet cables. figure 3 rj45 pin assignment 7 switching characteristics ? store and forward all data telegrams received by the switch are saved and their validity checked. invalid or faulty data packets (> 1522 bytes or crc errors) and fragments (< 64 bytes) are rejected. valid data telegrams are forwarded by the switch. the switch always forwards the data using the data transm ission speed that is used in the destination network segment. ? multi-address function the switch independently learns the addresses for termination devices, which are connected via a port, by evaluating the source addre sses in the data telegrams. only packets with unknown addresses, with a source address of this port or with a multicast/broadcast address in the destination address field are forwarded via the corresponding port. the switch can store addresses in its address table with an aging time of 5 minutes. this is important when more than one termination device is connected to one or more ports. in this way, several independent subnetworks can be connected to one switch. ? quality of service (qos): ieee 802.1p/q the fl switch sfn?-24vac switches are capable of reading ethernet packet s that have already been assigned a priority level by a managed switch. in cases of heavy traffic, packets with a priority level between 4 and 7 are considered high priority and processed before packets with a priority level between 0 and 3. after prioritization the packets are forwarded without modification. gnd us +? rj45 n.c. n.c. td- n.c. n.c. td+ rd- rd+ 8765 4321 a restart deletes the entire address table.
