Normalized active voltage or current signals

are transmitted galvanically isolated via the 2-

channel analog signal isolator IM31-22-I.

The device is equipped with two input circuits

of 0/2…10 V or 0/4…20 mA and two short-circuit proof output circuits of 0/4…20 mA

The transmission characteristic is adjusted via

a DIP switch on the front. In switch position

1:1 the input signal is transmitted without interference and made available at the outputs.

In LZ switch position, a dead-zero signal at

the input (0…10 V or 0…20 mA) is converted

and provided as a live-zero signal at the output (4…20 mA).

A green LED indicates operational readiness.
