MACX MCR-EX-T-UIREL-UP...
Temperature transducers with intrinsically safe
input for temperature sensors, voltage signals,
resistance-type sensors and potentiometers

Description
© PHOENIX CONTACT 2014-07-10
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).

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.
