MCR-UI-UI-NC Configurable 3-way isolating amplifier Phoenix

Description

Overview

Essential details：MCR-UI-UI-NC Configurable 3-way isolating amplifier Phoenix

MACX MCR-UI-UI 3-way isolating amplifiers are used to electrically isolate and convert standard analog signals. 3-way isolation prevents interference between different sensor circuits and thus improves the quality of the measuring circuit.
DIP switches can be used to reconfigure the inputs and outputs of the isolating amplifier, enabling more than 1600 signal conversions to be set.
When ordering preconfigured modules, specify the desired input and output signal combination (see order key). If the information is incorrect or unavailable, the devices will be supplied with the standard configuration (0 … 10 V input signal, 0 … 20 mA output signal).
Features
– 3-way electrical isolation
– More than 1600 signal combinations can be set using DIP switches (no software required)
– Up to SIL 2 according to EN 61508 for the live zero output
– Installation in zone 2 permitted
– Wide-range power supply including tolerance of 19.2 … 253 V AC/DC
– Step response (10 … 90%) of 35 µs (at 10 kHz), 11 ms (at 30 Hz)
– With screw or spring-cage connection
– Active and passive output
