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

or potential-free contacts can be connected

to the IMX12-DI03-1S-2R-S/24VDC isolating

switching amplifier. The device is equipped

with intrinsically safe input circuits and can be

installed in zone 2. The device can be toggled

between two operation modes by means of

a DIP switch: 1-channel operation with signal

doubling or 1-channel operation with alarm

output. 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.
