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

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

The following measuring ranges can be configured CI501-PNIO CI501-PNIO:

Voltage	0…10 V	1 channel used
Voltage	-10 V…+10 V	1 channel used

The function of the LEDs is described under Diagnosis and displays / Displays CI501-PNIO.

To avoid error messages from unused analog input channels, configure them as “unused”.
