Connector Function
X1 Power feed
X2 Continuation of the power to the next node
V1 System voltage: Power supply 1 (incl. supply of electronics)
V2 Load voltage: Power supply 2
NOTE
The system voltage (V1) and the load voltage (V2) are fed in and monitored separ-
ately. In case of an undercut of the admissible voltage, the connectors are switched-
off according to the module's supply concept. In case of an undervoltage at V2, the
LED PWR changes from green to red. In case of an undervoltage at V1, the LED PWR
is turned off.
7.2.1 Supply concept
The Device is supplied via two separate voltages V1 and V2.
The I/O-channels are therefore consequently separated into the different potential groups "de-
tachable I/O" (supplied through V2) and "non-detachable" I/O (supplied through V1). This al-
lows a safety shutdown of parts of an installation via emergency-off circuits.
V1 = supply of the module electronics and the respective slots
V2 = supply of module electronics and the respective connectors (separately detachable)
