Isolating switching amplifier

2-channel

IM1-22-R

The IM1-22-R isolating switching amplifier is a

2-channel device.

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

or potential-free contact transmitters can be

connected to the device.

The output circuits feature 2 relays, each with

1 NO contact.

Via six switches on the front, you can set the

operating behaviour for each channel sepa-

rately (work or quiescent current behavior, i.e.

NO/NC) as well as switch wire-break (WB)

and short-circuit monitoring (SC) on and off.

The Pwr LED lights green to indicate opera-

tional readiness. The 2-color LEDs 1 and 2

light yellow to indicate the switching status

of the associated output. In the event of an

input circuit error, the 2-color LED of the as-

signed faulty input turns red, with the input cir-

cuit monitoring switched on. Thereupon the

output relay drops out.
