Sensor supply
The sensor supply can be internal or external.
Wiring diagram - connecting a two-channel sensor equivalent via two channels
Per process signal, a two-channel sensor is connected equivalent via two channels to two
inputs of the F-module (1oo2 evaluation).
Any sensor supply of the module can be assigned to each input.
You can also supply the sensor by means of an external sensor supply.
