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.

You can toggle between working or closed

current, resp. NO or NC mode via three

switches at the front. The switching state of

channel 1 is thereby transmitted to the outputs

1 and 2.

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 relays drop out.
