Data sheet
The 6.2 mm wide MINI MCR-SL-UI-UI... is a configurable 3-
way isolating amplifier. It is used to electrically isolate, condi-
tion, amplify, and filter standard signals.
The standard analog signals 0...20mA, 4...20mA, 0...10V,
2...10V, 0...5V or 1...5V are available electrically isolated on
the input and output sides.
The DIP switches, which can be accessed on the side of the
housing, are used to configure the input and output signal
ranges.
The power supply (19.2 ... 30 V DC) can be supplied either via
connection terminal blocks "3"/"4" or "7"/"8" on the modules
or in conjunction with the DIN rail connector. Please refer to
the section titled "Power supply" for more information.
Features

5 Safety regulations and installation notes
5.1 Installation notes
– The category 3 device is suitable for installation in the
zone 2 potentially explosive area. It fulfills the require-
ments of EN60079-0:2009 and EN60079-15:2010.
– Installation, operation, and maintenance may only be car-
ried out by qualified electricians. Follow the installation in-
structions 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 certifi-
cates (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 manufac-
turer. 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 environ-
ment. 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.
5.2 Installation in the Ex area (zone 2)
– Observe the specified conditions for use in potentially ex-
plosive areas.
– The device must be installed in a housing (control or dis-
tributor box) which meets the requirements of EN 60079-
15 and provides at least IP54 (EN 60529) degree of pro-
tection.
– During installation and when connecting the supply and
signal circuits, observe the requirements of EN 60079-
14. 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 devic-
es from www.phoenixcontact.net/catalog.

6.4 Power supply
Supply via the module
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.
A 400 mA fuse should be connected upstream.
Supply via a power terminal block
The MINI MCR-SL-PTB power terminal block (Order No.
2864134) or the MINI MCR-SL-PTB-SP power terminal block
(Order No. 2864147), which are the same shape, are used to
feed the supply voltage to the DIN rail connector.
A 2 A fuse should be connected upstream.
Supply via a system power supply unit
The system power supply unit with 1.5A output current con-
nects the DIN rail connector to the supply voltage and can
therefore be used to supply several modules from the mains.
– MINI-SYS-PS-100-240AC/24DC/1.5 (Order No.
2866983)
– Potentially explosive areas:
MINI-PS-100-240AC/24DC/1.5/EX (Order No. 2866653)
NOTE: electrostatic discharge!
The device contains components that can be
damaged or destroyed by electrostatic dis-
charge. When handling the device, observe the
necessary safety precautions against electro-
static discharge (ESD) according to EN 61340-
5-1 and EN 61340-5-1.

6.5 Assembly
Figure 3 Mounting and removing
– Mount the module on a 35 mm DIN rail according to EN
60715.
– When using the DIN rail connector, first place it into the
DIN rail (see A – C). It is used to bridge the power supply.
It is also absolutely vital that you snap the module and the
DIN rail connector into position in the correct direction:
the snap-on foot should be at the bottom and the connec-
tor on the left.
6.6 Connecting the wires
The MINI MCR-SL-UI-UI... is available with two types of con-
nection:
– Screw terminal blocks (MINI MCR-SL-UI-UI)
– Spring-cage terminal blocks (MINI MCR-SL-UI-UI-SP)
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.
Spring-cage connection:
Figure 5 Spring-cage connection
•Insert a screwdriver into the opening above the connec-
tion terminal block.
•Insert the wire into the corresponding connection terminal
block.

8Adjustment
A potentiometer is located underneath the cover; this is used
for fine adjustment of the analog signals once the configura-
tion of the DIP switches has been modified.
The module is adjusted via its output final value:
•Connect the calibration source to the input of the isolating
amplifier and specify the final value of the set input signal.
•Use the potentiometer to set the exact final value of the
set output signal.
9 Connection/application example
Figure 6 Example application
Once the configuration of the DIP switches has
been modified, the potentiometer allows the
accuracy to be increased from < 0.4% to <
0.1%.
