 For connection of external devices to digital inputs, we recommend using a different (separate) power supply from the one used to power the device (unit/Extension) in order to retain galvanic isolation. Each digital input group also feature a DIGND terminal added specifically for connection of the separate power supply negative pole.  For connection of external devices to digital inputs, we recommend using a different (separate) power supply from the one used to power the device (unit/Extension) in order to retain galvanic isolation.
