Normalized active voltage or current signals

are transmitted galvanically isolated from the

Ex area to the non-Ex area via the 1-channel

analog signal isolator IM31-11EX-I.

The device is equipped with one input circuit

of 0/2…10 V or 0/4…20 mA and one short-circuit proof output circuit 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 the non-Ex area. In LZ switch position, a

dead-zero signal at the input (0…10 V / 0…20

mA) is converted and provided as a live-zero

signal at the associated output (4…20 mA).

A green LED indicates operational readiness.
