Terminal CPX-P
Key features – Power supply
Power supply concept
General information
The use of decentralised devices on
the fieldbus – particularly with high
protection for direct machine mount
ing – demands a flexible power supply
concept. A valve terminal with CPX-P
can, in principle, supply all voltages
via a single connection.
A distinction is made between supply
for
electronics plus sensors
valves plus actuators.
Connection technology:
7/8"
Interlinking blocks
Interlinking blocks represent the
backbone of the CPX-P terminal with
all supply lines. They provide the
power supply for the modules used on
them as well as their bus connections.
Many applications require the CPX-P
terminal to be segmented into voltage
zones. This applies in particular to the
separate disconnection of the outputs.
The interlinking blocks provide either
a space-saving central power supply
for the entire CPX-P terminal or
galvanically isolated, all-pin
disconnectable potential groups/
voltage segments.
