Edition • 2023-07-21T16:28:21+02:00 Relay coupler 1-channel IM73-12-R/24VUC The IM73-12-R/24VUC 1-channel relay cou- pler is particularly suitable for use as a cou- pling module for the safe galvanic isolation of binary signals. 2 synchronous controlled re- lays, each with 1 changeover contact are pro- vided at the output. If applied in SIL-3 circuits, the following condi- tions have to be observed: ■ If the output relay triggers a contactor di- rectly, the contactor must be equipped with a protective circuitry at the coil connection. ■ Both relays have to be connected in series. ■ The contact circuit is equipped with a fuse and is activated at 60 % nominal current. The status of the relay is indicated via LED on the front. ■ Output circuit: 2 relays each with 1 changeover contact ■ 5 A switching current at 250 VAC ■ Operating voltage 19…29 VDC ■ Removable terminal blocks ■ SIL3 ■ Galvanic isolation between input circuits and output circuits ■ TR CU
