4.2.2 Modbus RTU Master Module
Input module for connecting up to 32 Modbus RTU Slaves. The input module reads
the measured values and the status information from the Modbus RTU Slaves.
The connection of the following transmitters is supported:
– Dräger Polytron 8xx0
– GS01 via an ISA100 Gateway
– ISA100 UAPMO via an ISA100 Gateway
For further information, see the following chapter: "Module and port configuration
Modbus RTU Master Module", page 95.
The Modbus RTU master module has not been tested and approved for operation
in a safety and measuring function.
Typically 24 V, depending on the supply voltage of the
Docking Station.
With assignment of max. 4 inputs:
Max. 500 mA per channel
With assignment of 4 to 8 inputs:
Max. 250 mA per channel
Total transmitter output current per module max. 2 A.
If the 2 A is exceeded, the transmitters must be sup-
plied externally.

– wire break detection (loop current < 0.1 mA)
– Fault detection (loop current > 38 mA; this value
should be included when calculating the maximum
line resistances)
– Short circuit detection (loop current > 500 mA;
channel shuts down if this is exceeded)
– Total current monitoring (sum of loop currents on
all channels > 2000 mA; module shuts down if this
is exceeded)
