Output loop-powered 2-way isolator
MINI MCR-2-UI-I-OLP(-PT)(-C)
© PHOENIX CONTACT
Data sheet
The 2-way output loop-powered isolator with plug-in
connection technology, which can be configured using DIP
switches, is used for the electrical isolation, conversion, and
filtering of unipolar and bipolar standard and normalized
signals.
The device allows operation on an active analog input
module.
The device is powered via the current loop of the controller.
On the input side, standard analog signals and non-
standard analog signals can be connected, ranging from
2mA or 50mV up to 40mA or 30V. These are converted to
a 4mA...20mA signal.
There is no need for adjustment following a measuring
range changeover.
Features
– Output loop-powered 2-way isolator with plug-in
connection technology
– Approval for Ex-zone 2 (nA)
– 74 input ranges can be set via DIP switches
– Screw or push-in connection available
– Reinforced insulation according to IEC 61010-1
WARNING: Correct usage in potentially explosive areas
The module is a category 3 item of electrical equipment. It is absolutely vital to follow the instructions provided
here during installation and observe the information in the "Safety regulations and installation notes".
This device offers the option of NFC communication.
You can use the MINI Analog Pro Smartphone app to call-up DIP switch setting help and comprehensive
module information via the NFC interface of your Smartphone.
The MINI Analog Pro Smartphone app is available to you free.
Make sure you always use the latest documentation.

5 Safety regulations and installation notes
5.1 Installation notes
•The category 3 device is suitable for installation in
potentially explosive area zone 2. It fulfills the
requirements of EN 60079-0:2012 and EN 60079-
15:2010.
•Installation, operation, and maintenance may only be
carried out by qualified electricians. Follow the
installation instructions as described. When installing
and operating the device, the applicable regulations
and safety directives (including national safety
directives), as well as generally approved technical
regulations, must be observed. The safety data is
provided in this package slip and on the certificates
(conformity assessment, additional approvals where
applicable).
•While the devices are in operation, contact-dangerous
voltages may be present on the control elements. For
this reason parameterization, conductor connection,
and opening of the module lid are allowed only when
devices are in a de-energized state unless the
connected circuits are exclusively SELV or PELV
circuits.
•The device must not be opened or modified. Do not
repair the device yourself, replace it with an equivalent
device. Repairs may only be carried out by the
manufacturer. The manufacturer is not liable for
damage resulting from violation.
•The IP20 protection (IEC 60529/EN 60529) of the
device is intended for use in a clean and dry
environment. The device must not be subject to
mechanical strain and/or thermal loads, which exceed
the limits described.
•The device is not designed for use in atmospheres with
a danger of dust explosions.
•The device complies with the EMC regulations for
industrial areas (EMC classA). When using the device
in residential areas, it may cause radio interference.
•If the device is not used as described in the
documentation, the intended protection can be
negatively affected.
•To protect the device against mechanical or electrical
damage, install it in a suitable housing with appropriate
degree of protection as per IEC60529.
•Provide a switch/circuit breaker close to the device,
which is labeled as the disconnecting device for this
device.
•Provide for a overcurrent protection device (I 4 A) in
the installation.
•There is a double isolation of 300Veff between
neighboring modules of the same type oriented the
same way. The device has a base isolation of 150Veff
to other neighboring modules on the side with the DIP
switch.
•The voltages present at the input, output and supply are
extra-low voltages (ELV). Depending on the
application, dangerous voltage (>30V) against ground
could occur. For this event, safe electrical isolation from
the other connections has been implemented.
•The device must be stopped if it is damaged, has been
subjected to an impermissible load, stored incorrectly,
or if it malfunctions.
•Only use copper connecting cables providing the
permitted temperature range (60°C/75°C).
5.2 Installation in Zone 2
•Observe the specified conditions for use in potentially
explosive areas! Install the device in a suitable
approved housing (with a minimum of IP54 protection)
that meets the requirements of EN 60079-15. Observe
the requirements of EN 60079-14.
•Only devices which are designed for operation in Ex
zone 2 and are suitable for the conditions at the
installation location may be connected to the circuits in
the Ex zone.
•In potentially explosive areas, terminals may only be
snapped onto or off the DIN rail connector and wires
may only be connected or disconnected when the
power is switched off.
•The device must be stopped and immediately removed
from the Ex area if it is damaged, was subject to an
impermissible load, stored incorrectly or if it
malfunctions.
5.3 UL Notes
INDUSTRIAL CONTROL EQUIPMENT FOR
HAZARDOUS LOCATIONS 45FP
1 Suitable for use in class 1, division 2, groups A, B, C and
D hazardous locations, or nonhazardous locations only.
2 WARNING - EXPLOSION HAZARD: Do not disconnect
equipment unless power has been removed or the area
is known to be non-hazardous.
3 WARNING - EXPLOSION HAZARD: Substitution of any
components may impair suitability for Class I, Division
2.
4 This device is open-type and is required to be installed
in an enclosure suitable for the environment and can
only be accessed with the use of a tool or key.

– Mount the module on a 35 mm DIN rail according to EN
60715.
An ME 6,2 TBUS-2 DIN rail connector (Order No.: 2869728)
is used to supply active devices. A DIN rail connector is not
necessary for operation of this loop-powered device.
This device can be snapped onto a DIN rail connector – an
electrically conductive connection is not established. This
means that you do not need to disconnect an existing DIN
rail connector element connection.
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.

6.6 FASTCON Pro plugs
The device has pluggable connection terminals with an
integrated test disconnect terminal block, with either push-in
or screw-in connection technology.
You can plug or screw the FASTCON Pro plugs onto the device directly
without tools. You can use the integrated spindle screw to easily remove
the plugs from the module or set the isolating position, even when the
plugs are connected. For this purpose, use a screwdriver of sufficient
width, e.g. SZF1-0.6x3.5 (order number: 1204517).
The spindle screw will turn by itself when the FASTCON Pro
plugs are connected. There is no need for you to fix the
spindle screw in place as well.
4-way coding prevents incorrect insertion into the module.
Screw connection:
Figure 4 Screw connection
•Insert the wire into the corresponding connection terminal block.
•Use a screwdriver to tighten the screw in the opening
above the connection terminal block.
Push-in connection:
Figure 5 Push-in connection
•Insert the wire into the corresponding connection terminal block.
6.7 Current measurement
The device allows current measurement without
disconnection of the conductors by means of integrated test
disconnect terminals.
Test sockets which support current measurement are
marked TI+ or TI-.
For the current measurement, use 2 mm probe tips of the
type Fluke TL75-1 or probe tips with a comparable tip shape.
Figure 6 Test disconnect terminal block
Furthermore, individual circuits can be specifically
disconnected, e.g. for commissioning.
You can set the isolating position by turning the integrated
spindle screw through 180°. The isolating position is
indicated by the marking on the plugs.
Figure 7 Disconnect position
6.8 Marking
Standard UCT-EM... or UC-EMLP tags are available for
marking the devices and can be printed as per customer
requirements. In addition, the covers provide enough space
for the use of freely chosen sticky labels such as SK 5.0
WH:REEL without concealing the LED diagnostic
indicators.
