2.5.3 Voltage supply concept – formation of voltage zones
2-14
The modular power supply arrangement of the CPX terminal
facilitates the formation of voltage zones.
Observe the following:
– The internal electronics of the I-port devices are supplied
from the operating power supply for electronics/sensors
(V ).
EL/SEN
The I-port valve terminals and output modules are
provided with load voltage from the load voltage for the
valves (V ).
VAL
Note
The CTEL master module must be supplied via the same
potential (common power supply unit) as the operating
power supply for the electronics/sensors (V
CPX terminal (see also Fig. 2/2).
The supply of the actuators can take place via the
load voltage supply V
V .
EL/SEN
Basic information on the power supply arrangement of the
CPX terminal can be found in the CPX system description.
You will find some specific application cases in Fig. 2/2,
Fig. 2/3 and Fig. 2/4.
