Connection of active-type analog sensors (current) with electrically isolated power supply to the analog inputs

Current 0…20 mA 1 channel used
Current 4…20 mA 1 channel used

For the measuring ranges that can be configured, please refer to the sections Measuring Ranges CI581-CN and Parameterization CI581-CN.

Unused input channels can be left open-circuited, because they are of low resistance.
