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.
