3. Intended Use
3.1.General
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
The product is intended to be installed in a suitable external enclosure.
The device is used in control and instrumentation technology for transfer of
signals such as 20mA and 10V standard signals.
The device has intrinsically safe circuits that are used for operating intrinsically
safe field devices in hazardous areas. Use the device only within the specified
ambient and operating conditions. The device is designed for mounting on a 35
mm DIN rail. The device is intended to be powered by 24V NEC class 2,
IEC/EN/UL 60950-1 LPS or IEC/EN/UL 601010-1 Limited Energy power source.
Indoor use only or outdoor use when installed in an external enclosure suitable
for outdoor use.
The device may be installed in the non-hazardous area.
3.2.Technical Specification
This Input Module intrinsically safe transfers Analog signals from
4-20mA, 0-10V, PT1000, DI. Convert to digital signal, store and send by protocol
Modbus RS485.
Each channel could be settable by a jumper to read any analog signal before
mentioned. The Input Module intrinsically safe prevents the transfer of
unacceptably high energy from the safe area into the hazardous area.
The zener diodes in the Zener Barrier are connected in the reverse direction. The
breakdown voltage of the diodes is not exceeded in normal operation. If this
voltage is exceeded, due to a fault in the safe area, the diodes start to conduct,
causing the fuse to blow. The Zener Barrier has a positive polarity.

4. Mounting
Do not mount the device in the dust hazardous area.
Maximum supply voltage 24Vdc.
Operation ambient temperature -20°C to +45°C.
Altitude up to 2,000 m.
Maximum relative humidity 80 % for temperatures up to 31 °C
decreasing linearly to 50 % relative humidity at 40 °C.
The device fulfills a degree of Protection IP20 according to EN 60529
The Zener Barrier is secured to a DIN rail using a tab and screw.
Additionally, a snap-in spring mounting system and can be removed with
an Allen to remove the screw and then a flat head screw driver by
inserting the screw driver head in steel tab on the DIN rail side and
pulling or prying to overcome the spring’s force.

5. Equipment installation and operation.
5.1Connections to the supply
Danger!
Danger to life from incorrect installation
Incorrect installation of cables and connection lines can compromise the
function and the electrical safety of the device.
• Observe the permissible core cross-section of the conductor.
• When using stranded conductors, crimp wire end ferrules on the
conductor ends.
• Use only one conductor per terminal.
• When installing the conductors, the insulation must reach up to the
terminal.
• Observe the tightening torque of the terminal screws.
• Supply voltage fluctuations up to ±10 % of the nominal voltage.
1. Ground the device. Use the DIN rail to ground connection of the
Zener barrier for grounding.
2. Connect the field circuit.
3. Connect the power supply & Modbus communication.

10
The DIN rail connector is integrated into the DIN rail. The bus connector
has 5 positions for energy supply and data transmission. It connects
several zener barrier modules, which are mounted on the DIN rail.
5.2 Equipment Operation
The barrier should be connected into the circuit while it is unpowered.
The voltage through the barrier under normal operation should not
exceed the rated Uo voltage. DC voltages and AC voltages of up to 1 MHz
pass through the barrier without attenuation. Any voltage above the
rated voltage is clamped to the rated voltage until the current exceeds
40 mA at which time an internal fuse is blown. Resistors are included in
the device to limit the available current in the Hazardous area. The
device protects the Hazardous area from high voltages and currents
which may cause sparks. The barrier must be connected using the proper
wires, wire gauge and codes as shown in the drawing on chapter
“Electrical wiring drawings” & “Electrical/Electromechanical drawings”.
