The analogue input processes measured-value data supplied by analogue sensors. Four analogue transducers in any combination can be connected to the input. The analogue input evaluates voltage and current signals.
Voltage signals: 0 ... 1 V DC 0 ... 10 V DC
Current signals: 0 ... 20 mA DC 4 ... 20 mA DC
The 4 ... 20 mA current inputs can be monitored for open-circuit conditions.
The analogue input needs a separate power supply, for example the power supply module ref.-no. WSSV 10.
