The 1-channel IM1-12EX-R isolating switching

amplifier is equipped with an intrinsically safe

input circuit.

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

or potential-free contact transmitters can be

connected to the device.

The output circuit features 2 relays each with

an NO contact, one of which works as an

alarm outpu

You can toggle between working or closed

current, i.e. NO or NC mode, via three switches at the front. The switching state of channel

1 is thereby transmitted to output 1.

When using mechanical contacts, wire-break

and short-circuit monitoring must be switched

off or the contacts must be wired to resistors

(II) (see circuit diagram).

The Pwr LED lights green to indicate operational readiness. The 2-color LED 1 lights yellow to indicate the switching status of the output. In the event of an input circuit error, the 2-

color LED turns red, with the input circuit monitoring switched on. Thereupon the output and

the alarm relay drop out.
