Multiple use of sensors
Not all sensor signals can be routed via bus to another device.
For this reason, function "Multiple use of sensors" allows for wiring a passive signal
at an input terminal directly to a Y-output and provide it as a DC 0…10 V signal.
The signal can then be fed to other devices.

Conversion of a Ni 1000 or Pt 1000 signal to a DC 0...10 V signal is made via
