MACX MCR-EX-IDS-I-I(-SP)
Output signal conditioner, Ex i, 1-channel

Description
© PHOENIX CONTACT 2020-08-24
The output signal conditioner helps in controlling the
intrinsically safe (Ex-i) I/P converters, control valves and
indicators installed in the Ex area.
The device isolates and transmits 0/4 mA ... 20 mA signals
to the Ex area with intrinsic safety.
For operating the intrinsically safe SMART actuators, the
analog measuring value can be overlayed with digital
communication signals (HART) on the Ex or non-Ex side and
transmitted bidirectionally in an electrically isolated manner.
Sockets are integrated into the COMBICON connectors for
connecting HART (HHT) communicators.
The device enables open-circuit and short-circuit
monitoring.
You can switch the short-circuit detection on or off using the DIP
switch.
An open or short-circuited field circuit causes a high input
impedance on the controller side, thus enabling open-circuit
and short-circuit monitoring via the control system.
Readiness for operation is indicated via a green LED.
The device is approved for safety-related applications up to
SIL 2 (1oo1) / SIL 3 (1oo2).

To protect the device against mechanical or electrical
damage, install it in suitable housing with an appropriate
degree of protection according to IEC/EN 60529.
During maintenance work, disconnect the device from
all effective power sources.
If the device is not used as described in the
documentation, the intended protection can be
negatively affected.
Thanks to its housing, the device has basic insulation to
the neighboring devices, for 300 Veff. If several devices
are installed next to each other, this has to be taken into
account, and additional insulation has to be installed if
necessary! If the neighboring device is equipped with
basic insulation, no additional insulation is necessary.
The voltages applied at the input, output, and power
supply are extra-low voltages (ELV). Depending on the
application, it can be the case that a voltage that is
dangerous to the touch (>30 V AC / >60 V DC) against
the ground could be present on the device. In this case,
a safe galvanic isolation exists between the input side
and the output side.
109172_en_00
The device must be clearly marked as nonintrinsically safe.

Electrostatic discharge
NOTE: Electrostatic discharge
The device contains components that can be
damaged or destroyed by electrostatic
discharge. When handling the device, observe
the necessary safety precautions against
electrostatic discharge (ESD) according to EN
61340-5-1 and IEC 61340-5-1.

Where the total current consumption of the aligned modules
does not exceed 400 mA, the power can be supplied directly
at the connection terminal blocks of the module.
Up to 16 modules can be supplied depending on the current
consumption of the modules.
We recommend connecting a 630 mA fuse (normal-blow or
slow-blow) upstream.
Supply via power and error message module
The MACX MCR-PTB (Order No. 2865625) or the MACX
MCR-PTB-SP (Order No. 2924184) supply and error
message module is used to provide the supply voltage to the
DIN rail connector.
Simple or redundant diode-decoupled power supply is
possible.
Depending on the current consumption of the modules, up
to 150 individual modules can be supplied by a supply that
is protected by a fuse.
The module has integrated error evaluation. An auxiliary
supply failure or fuse fault is indicated at a relay contact and
displayed via a flashing LED.

Mounting and removing
Mount the device on a 35 mm DIN rail according to
EN 60715.
When using the DIN rail connector, first insert it in the 35
mm DIN rail according to EN 60715 (A - C).
DIN rails with a height of 7.5 mm or more can be used.
The DIN rail connector is used to bridge the power
supply and communication.
The snap-in direction of the device and DIN rail
connector must be observed: snap-on foot on the
bottom and plug on the left.
Install the module in a suitable housing to meet the
requirements for the protection class.
