Connection example

Note

By connecting the sensor’s negative pole of the output voltage to AGND, the electrically isolated voltage source of the sensor is referred to ZP.

The following measuring ranges can be configured for AX521 AX521 - Analog Input/Output Module and for AX522 AX522 - Analog Input/Output Module:

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

In order to avoid error messages or long processing times, it is useful to configure unused analog input channels as “unused”.
