1. Description

The MCR-CLP-UI-I-4 loop powered isolator is used

for electrical isolation and signal matching in analog

signal circuits.

On the input side there are more than 25 different

signal ranges available, which can be set using DIP

switches.

On the output side the isolator is operated in a

4…20 mA current loop, which simultaneously provides

the module with the required power for signal

conversion.

On the front face of the housing, adjustment of

± 2%

of the signal value can be made using the zero/span

potentiometers.

The loop powered isolator is especially suitable for

signal matching and for electrically isolating active PLC

input board cards. If no order references are specified,

the device is provided with the default input range of

4…20 mA.
