cessed.
– Approval for Ex-zone 2 (nA)
The standard analog signals 0 ... 20 mA, 4 ... 20 mA, 0 ... 10 V,
– Screw or spring-cage connection can be provided

on the output side.
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.
Attention: Correct usage in potentially explosive areas

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

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.

Never connect the supply voltage directly to the
DIN rail connector. It is not permitted to draw
power from the DIN rail connector or from individual modules.
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.

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 connects the DIN rail connector to the supply voltage and can
therefore be used to supply several modules from the mains.

Use a screwdriver to tighten the screw in the opening
above the connection terminal block.
Spring-cage connection:
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 connector on the left.

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.
Once the configuration of the DIP switches has
been modified, the potentiometer allows the
accuracy to be increased from < 0.4% to <
0.1%.
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.
