Description
The 6.2 mm slim configurable 3-way isolation amplifier MINI Features
MCR-SL-SHUNT-UI(-SP)(-NC) converts mV voltages to
– Configurable 3-way isolating amplifier
standard signals. The signals are amplified, filtered, and elec– Input and output signal range configurable via DIP
trically isolated.
switches
The 3-way isolation amplifier makes it possible, for example,
– Approval for Ex-zone 2 (nA)
to measure DC currents flowing through a shunt resistor.
– Can be supplied with screw or spring-cage connection
The voltage drop of a few mV via the resistor is applied at the
isolation amplifier and is converted to a standard signal by the – Can be supplied configured or unconfigured
isolation amplifier.
The DIP switches, which can be accessed on the side of the
housing, are used to configure the input and output signal
ranges.
Power (19.2 V DC to 30 V DC) can be supplied through connection terminal blocks on the modules or in conjunction with
the DIN rail connector.
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".
Make sure you always use the latest documentation.

–
–
The category 3 device is suitable for installation in the
zone 2 potentially explosive area. It fulfills the requirements of EN 60079-0:2009 and EN 60079-15:2010.
Installation, operation, and maintenance may only be carried out by qualified electricians. Follow the installation instructions described. When installing and operating the
device, the applicable regulations and safety directives
(including national safety directives), as well as general
technical regulations, must be observed. The technical
data is provided in this package slip and on the certificates (conformity assessment, additional approvals
where applicable).
It is not permissible to open or modify the device. Do not
repair the device yourself but 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 degree of protection (IEC 60529/EN 60529) of
the device is intended for use in a clean and dry environment. Do not subject the device to any load that exceeds
the described limits.
The device is not designed for use in atmospheres with a
danger of dust explosions.

Installation in the Ex area (zone 2)
Observe the specified conditions for use in potentially explosive areas.
The device must be installed in a housing (control or distributor box) which meets the requirements of EN 6007915 and provides at least IP54 (EN 60529) degree of protection.
During installation and when connecting the supply and
signal circuits, observe the requirements of EN 6007914. Devices may only be connected to circuits in zone 2 if
they are suitable for operation in Ex zone 2 and for the
prevailing conditions at the place of use.
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, has been subjected to
an impermissible load, has been stored incorrectly, or if it
malfunctions.
You can download the latest documents for these devices from www.phoenixcontact.net/catalog.

Configuration
If the modules are not configured (all DIP switches set to position 0), the module does not have a defined function until the
DIP switches have been set.
If the modules are preconfigured, please specify the order
number and the complete order key.
If the order key is incomplete, the standard configuration will
be supplied.
DIP switch S1 specifies the output signal depending on the
input signal.
DIP switch S2 specifies the input signal.
Standard Configuration
"NC" versions (...-NC) have the following standard configuration:
– Input: 0 mV...50 mV
– Output: 0 mA...20 mA
– Limit frequency: 100 Hz
(All DIP switches are set to the "off" position, transmission
error < 0.2 %.)

Adjustment
A potentiometer is located underneath the cover; this is used
for fine adjustment of the analog signals once the configuration of the DIP switches has been modified.
The potentiometer can be used to adjust the amplification by
±1.25%.
Please note that measuring equipment with appropriate measuring accuracy is required for
precise adjustment.
The module is adjusted via its output final value:
•
•
Connect a calibration source to the input of the isolation
amplifier and specify the final value of the set input signal.
Use a potentiometer to set the exact final value of the set
output signal.
