2.3.3 Power supply concept Formation of power zones

2−16
The CPX terminal's modular power supply concept facilitates
the formation of power zones.
Please note the following:
CP input modules are supplied from the operating power
supply for electronics/sensors (V
CP valve terminals and CP output modules are supplied
with the load supply for valves (V
The CPX−CP interface connects the internal contact rails
0 V and 0 V
EL/SEN
The electrical isolation of the operating power supply
for electronics/sensors (V
and of the load supply supplying the CPX−CP interface
for valves (V
longer functions.
Complete electrical isolation (all poles) of the valve
supply of the CP valve terminals is therefore not also
possible in conjunction with a CPX valve supply, type
CPX−EV−V.
Please note
The CPX−CP interface must be supplied via the same po
tential (common power unit) as the operating power sup
ply for electronics/sensors (V
(see also Fig. 2/5).
Basic information on the power supply concept of the CPX
terminal can be found in the CPX system manual.
You will find some specific applications in Fig. 2/3, Fig. 2/4
and Fig. 2/5.
