hi,

3-wire-transducers are like 4-wire-transducers with a combined M.

so Measuring range module should be set to C.

Wiring is described here:

Analog input module SM 331; AI 8 x 12 bit;(6ES7331-7KF02-0AB0)

24VDC of the sensor is clear. The one wire for measuring goes on "+" of the chanel and the "-" of the chanel goes to M of the same potential of the power-supply of the sensor.

hope this helps,

regards,

Thanks
