Wiring Diagram for Use Case 2.2 – Connecting One Two-Channel Sensor Via Two Channels
One two-channel sensor is connected via two channels to two inputs of the F-module for
each process signal (1oo2 evaluation).
The wiring is carried out at the appropriate connection module.
The figures below illustrate an example wiring diagram for channel groups 1 and 2.
