MACX MCR-EX-T-UIREL-UP...

Temperature transducers with intrinsically safe

input for temperature sensors, voltage signals,

resistance-type sensors and potentiometers

Data sheet

104602_en_06

Description

The configurable and programmable

MACX MCR-EX-T-UIREL-UP...

temperature transducer is

used for the intrinsically safe (Ex i) operation of all standard

temperature sensors (RTDs and thermocouples), voltage

signals, remote resistance-type sensors and potentiome-

ters. The temperature input signals are output in a linearized

format at the output. In addition to an analog current and

voltage output, the module also has three switching outputs.

If you use the device in safety-related applications, relay 2

and 3 are connected to create a safety-related switching

output. The power supply has been designed as a wide

range power supply.

The devices can be installed in zone 2 in the protection type

"n" (EN 60079-15).

Features such as sensor type, connection method, measur-

ing range, measuring unit, filter, alarm signal and output

range can be configured using the ANALOG-CONF soft-

ware and a device-specific DTM (Device Type Manager).

Features

–

Input for all standard temperature sensors (RTDs and

thermocouples), voltage signals, remote resistance-

type sensors and potentiometers.

With intrinsically safe inputs [Ex ia] IIC

Current and voltage output

Switching output (3 PDT relay)

Switching output SIL: 1 relay

Configuration via software (FDT/DTM, ANALOG-

CONF) or operator interface (IFS-OP-UNIT)

Up to SIL 2 according to EN 61508 on output 4 ... 20 mA

3-way electrical isolation

Installation in zone 2 permitted

Wide range power supply 19.2 ... 253 V AC/DC

With screw or spring-cage connection

(push-in techno-

logy)

–

WARNING: Explosion hazard

The device is an item of associated electrical equipment for intrinsically safe circuits. It is designed for

use in zone 2, if specific conditions are observed.

When installing and operating the device, the applicable safety directives (including national safety directives), ac-

cident prevention regulations, as well as general technical regulations must be observed.

WARNING: Explosion hazard

Please observe the safety regulations and installation notes on page 8.

Make sure you always use the latest documentation.
