The IM73-12-R/24VUC 1-channel relay coupler is particularly suitable for use as a coupling module for the safe galvanic isolation of

binary signals. 2 synchronous controlled relays, each with 1 changeover contact are provided at the output.

If applied in SIL-3 circuits, the following conditions have to be observed:

■ If the output relay triggers a contactor directly, 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
