7.2.1 Supply Concept
All TBEN-S-devices are supplied via two separate voltages V1 and V2.
The I/O-channels are therefore consequently separated into the different potential groups "detach-
able I/O" (supplied through V2) and "non-detachable" I/O (supplied through V1).
This allows a safety shutdown of parts of an installation via emergency-off circuits even when using
the highly flexible 16DXP-module variants.
V1 = supply of module electronics and the respective connectors
V2 = supply of device electronics and the respective connectors (separately detachable)
