Ground isolation diagram
Switch J6 settings:
Open
The ground (DICOM) of digital inputs
DI1 … DI5 and DIL is separated from the
ground (DIOGND) of digital inputs / outputs
DIO1, DIO2 and DI6. The insulation
voltage between them is 50 V.
Closed,
default
All digital inputs and outputs share the
same ground, default.
