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

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

The measuring ranges are described in the section Measuring Ranges CI592-CS31 - Digital and Analog Inputs and Outputs CI592-CS31 - Digital and Analog Inputs and Outputs:

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