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

The following measuring ranges can be configured EtherCATâ Bus Module CI511-ETHCAT EtherCATâ Bus Module CI511-ETHCAT:

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

The function of the LEDs is described under Diagnosis and Displays / Displays EtherCATâ Bus Module CI511-ETHCAT.

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