Product Description

The Phoenix Contact MINI MCR-2-UI-I-OLP is a compact, loop-powered, two-way isolator designed for the electrical isolation, conversion, and filtering of unipolar and bipolar analog signals in industrial applications. It accepts a wide range of input signals—from 2 mA or 50 mV up to 40 mA or 30 V—and converts them to a standard 4 mA to 20 mA output. The device is powered directly through the current loop from the controller, eliminating the need for an external power source. Input configurations are easily set via DIP switches, and the unit is available with either screw or push-in connection technology to suit different installation preferences.
