*Ground selector (DICOM=DIOGND) settings
DICOM=DIOGND: ON
All digital inputs share a common ground (DICOM connected to DIOGND). This is the default setting.
DICOM=DIOGND: OFF
Ground of digital inputs DI1…DI5 and DIIL (DICOM) is isolated from DIO signal ground (DIOGND). Isolation
voltage 50 V.
**The maximum common mode voltage between each AI input and AGND is +30 V
