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.

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

The following measuring ranges can be configured PROFINETâ IO Bus Module CI501-PNIO PROFINETâ IO Bus Module 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 Displays.

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