Several (or all) analog inputs can be configured as digital inputs CI541-DP. The inputs are not electrically isolated against the other analog channels.

The following figure shows the connection of digital sensors to the analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.

The following measuring ranges can be configured CI541-DP CI541-DP:
