1 Voltage supply, signal output
2 For display and adjustment module or interface adapter
3 For external display and adjustment unit
4 Ground terminal for connection of the cable screening
To make a second measured value available for use, you can use the
supplementary electronics "
Additional current output
".
Both current outputs are passive and need a power supply.
