Positions of the measuring range modules
The position enables you to specify the transducer to be connected to the respective channel
group.
Position
Type of measurement
A
Thermocouple / resistance measurement
B
Voltage (factory setting)
C
Current (4-wire transducer)
D
Current (2-wire transducer)
In our example, a sensor with a 4 to 20mA 2-wire transducer is connected to channel group
1 at input 0.
A 4-wire transducer is connected to channel group 2 at inputs 2 and 3.
Therefore, the first measuring range module should have position D and the second should
have position C.

Description
1
With a screwdriver, pull out the
two measuring range modules
2
Turn the measuring range module
to the desired position:
3
Plug the measuring range module
back into the module
In our example, the module
should have the following
positions:
CH0,1: D
CH2,3: C
