Sensors or potential-free contacts can be connected to the IM12-DI01-2S-2T-/24VDC isolating switching amplifier in accordance with

EN 60947-5-6 (NAMUR). 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 potential-free transistors with high cut-off

frequency (10 kHz). 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. Then, the transistor of the corresponding output circuit locks.

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.
