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

or potential-free contacts can be connected to the IM12-DI03-1S-2T-S/24VDC isolating switching amplifier. The device can be installed in zone 2. The device can be switched

between 1-channel operation with signal doubling or 1-channel operation with alarm message output using DIP switches. The output

circuits are equipped with two potential-free

transistors. 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 green LED indicates operational readiness. An error in the input circuit causes the

red LED to flash 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.
