In order to avoid error messages or long processing times, it is useful to configure unused
analog input channels as "unused".
Connection of active-type analog sensors (Current) with galvanically isolated power supply
The following figure shows the connection of active-type analog sensors (current) with galvani-
cally isolated power supply.

Unused input channels can be left open-circuited, because they are of low resistance.
Connection of active-type analog sensors (Voltage) with no galvanically isolated power supply
The following figure shows the connection of active-type sensors (voltage) with no galvanically
isolated power supply.
