Sensors according to EN 60947-5-6 (NAMUR)

or potential-free contacts can be connected

to the IM12-DI01-2S-2R-PR/24VDC isolating switching amplifier. The device can be installed in zone 2 and a DIP switch on the device allows toggling between 2-channel or

1-channel operating mode with signal doubling. The output circuits are equipped with

two changeover relays. The device can be

powered from a power bridge that also transmits a collective fault signal. The device complies with the requirements of the NE21.

The devices feature DIP switches on the

front. This allows to select between the output

mode, the input circuit monitoring, as well as

toggle between signal duplication and 1-channel operation. When using mechanical contacts, either line monitoring must be switched

off or the contact must be wired with resistors

(see wiring diagram).

The Pwr LED lights green to indicate operational readiness. An error in the input circuit leads to a flashing red LED according

to NE44. Thereupon the relay of the belonging output circuit drops out and the common

alarm output becomes conducting.

The device can be used in safety circuits up to

SIL2 (high and low demand according to IEC

61508).

The device is equipped with removable screw

terminals.
