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

The following figure shows the connection of active-type analog sensors (current) with electrically isolated power supply to the analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.

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

The following measuring ranges can be configured CANopenâ Bus Module CI581-CN CANopenâ Bus Module CI581-CN:

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 CANopenâ Bus Module CI581-CN.

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