Description
The 2-channel repeater power supply is designed for the
operation of intrinsically safe (Ex-i) 2-wire measuring transducers installed in the Ex area.
The 2-wire measuring transducers are supplied with power
and analog 4...20 mA measured values from the Ex area are
transferred to the non-Ex area.
The output of the module is active.
The analog measured value on the Ex or non-Ex side can be
overlayed with digital (HART) communication signals and
transmitted bidirectionally.
Sockets are integrated into the COMBICON connectors for
connecting HART communicators.
The module is suitable for safety-related applications up to
SIL 3 according to IEC/EN 61508.

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.
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.
Safety-related applications (SIL)
When using the device in safety-related applications, observe the instructions in “Safety-related applications”, as the
requirements differ for safety-related functions.
Intrinsic safety
The device is approved for intrinsically safe (Ex-i) circuits up to Ex zone 0 (gas) and Ex zone 20 (dust). The
safety technology values for intrinsically safe equipment
and the connecting lines must be observed for the hookup process (IEC/EC 60079-14) and the values specified
in this installation note and/or the EC examination certificate must be observed.
When carrying out measurements on the intrinsically
safe side, observe the relevant regulations regarding
the connection of intrinsically safe equipment. Use only
these approved measuring devices in intrinsically safe
circuits.
If the device was used in circuits which are not intrinsically safe, it is forbidden to use it again in intrinsically
safe circuits. Label the device clearly as being not intrinsically safe.

EN / UL 61010-1:
• Provide for a switch/circuit-breaker in the
vicinity of a device that is marked as disconnect device for this device.
• Provide overcurrent protection (I ≤ 16 A)
within the installation.
• To protect the device against mechanical
or electrical damage, install it in a suitable
housing with appropriate degree of protection as per IEC 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 present at the input, output,
and supply are extra-low voltages (ELV).
Depending on the application, hazardous
voltage (> 30 V) to ground may occur.
Safe electrical isolation between inputs
and outputs and between the inputs and
the supply exists for such cases.

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.
Before startup, check that the device is operating and
wired correctly, in particular with regard to the wiring

Comparison of the safety data
NOTE
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.
The supply voltage can be supplied via terminal points 1.1
and 1.2 or via the DIN rail connector.
WARNING: Explosion hazard
Compare the safety data before connecting a
device located in the Ex i area to this device.
Provide proof of intrinsic safety according to standard IEC/
EN 60079-14 and other national standards and installation
specifications, if applicable.
Safety data
Supply via the MACX Analog Ex 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.
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.

Output values outside this range are considered as the safe
state, which is detected by the subsequent controller.
Safe failures in the device are therefore errors where the device sends output signals that deviate from the relevant input
signals by no more than 2%.
Dangerous failures are errors where the device does not follow a change in the input signal or deviates from the input signal by more than 2% and is not outside the range.
Errors that can be detected as dangerous failures are those
which send a signal outside the standard range (< 3.6 mA
and > 21 mA).
The failure rates in FIT for the entire device are as follows:
PFH = 5.53 * 10-8/h
The device is therefore suitable for SIL 3 applications.

Installation and startup
NOTE: Installation, operation, and maintenance may only be carried out by qualified
specialist personnel.
PFH = 1.99 * 10-8/h
When calculating the average probability of a dangerous failure on demand, errors with the same cause were taken into
consideration and a β or βD factor of 2% was determined.
The device is therefore suitable for SIL 3 applications.
In SIL 2 applications, if the percentage of the device for the
entire safety chain is assumed to be a maximum of 10%, a
maintenance/test interval of 10 years can be achieved.
