(signal source: PV.source → Analog).
Tab. 5: X2 – M12 socket, 5-pole, input signals process actual value (only
available for devices with process controller function)
NOTE!
For reasons of wire resistance compensation, connect the
Pt 100 sensor via 3 wires. Always bridge Pin 4 and Pin 5 on
the sensor.
Connection lines may be a maximum of 20 m long.

and with the appropriate tools.
Using the set-point value input 4...20 mA
If several devices of Type 3360 or 3361 are connected in
series and the power supply to a device in this series con-
nection fails, the input of the failed device becomes highly
resistive. As a result, the 4...20 mA standard signal fails.
