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.
