Voltage concept within an field multiplexer station
4.2.1
Power and segment terminals
Power terminal
The power terminal interrupts the potential jumpers for the main circuit U
M
, the segment
circuit U
S
, and the reference potential GND. To do this, the voltages are to be recreated.
This principle is shown schematically in Figure 4-1 for a section of a field multiplexer station.
Figure 4-1
Example: Interruption/recreation of the potential jumpers through the power
terminal
Segment terminal
The segment terminal interrupts the potential jumper U
S
of the previous terminal an
recreates it (segment circuit U
S
). To do this, the voltage is tapped off from the potential
jumper U
M
.
This principle is shown schematically in Figure 4-2 for a section of a field multiplexer station.

S
through the
segment terminal
Please refer to the IL SYS INST UM E user manual for detailed information on the voltage
concept within an Inline station, which also applies for a field multiplexer station.
