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

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

The measuring ranges are described in the section Measuring Ranges CI511-ETHCAT CI511-ETHCAT.

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