Description
© PHOENIX CONTACT 2012-05-21
The configurable and programmable
MACX
MCR-T-UI-UP...
temperature transducer is used for the op-
eration of all standard temperature sensors (RTDs and ther-
mocouples), voltage signals, remote resistance-type sen-
sors and potentiometers. 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 a
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). The sensors are then operated in an in-
trinsically safe (Ex ic) manner.
The temperature transducer can be configured with the
standard configuration (see example: “Order key” on
page 7) or order-specific according to the order key and is
delivered calibrated and ready for operation. Possible set-
tings for the modules configured according to the order
(MACX MCR...-C) can be found in the order key on page
page 7.
The set configuration is shown on the label on the side of the
housing.
Features such as sensor type, connection method, measur-
ing range, measuring unit, filter, alarm signal and output
range can be configured using the IFS-CONF software and
a device-specific DTM (Device Type Manager).
WARNING: Danger of explosion
The device is designed for use in zone 2 and has an intrinsically safe (Ex ic) measured current circuit if
the 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 12.
Make sure you always use the latest documentation.
