Connection of Active-type Analog Sensors (Voltage) with no Electrically \ Isolated Power Supply to the Analog Inputs

The following figure shows the connection of active-type analog sensors (voltage) with no electrically isolated power supply to the analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.

Attention

:strong:Risk of faulty measurements!

The negative pole/earthing potential at the sensors must not have too large a potential difference with respect to ZP (max. ± 1 V within the full signal range).

Make sure that the potential difference never exceeds ± 1 V.

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

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