Sensors or potential-free contacts can be connected to the IMX12-DI01-2S-2R-0/24VDC

isolating switching amplifier in accordance

with EN 60947-5-6 (NAMUR) . The device is

equipped with intrinsically safe input circuits

and can be installed in zone 2. A DIP switch

on the device allows to toggle between 2-

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

with two changeover relays. 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.

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.
