Pneumatic interface for
MPA pneumatics The pneumatic interface for MPA pneumatics provides the
mechanical and electrical connection to the MPA pneumatic
modules. Therefore, from the point of view of the CPX termiĆ
nal, the MPA pneumatic interface does not count as an elecĆ
tric module. Instead, the individual MPA pneumatic modules
each represent an electric module with digital outputs for
triggering the integrated valves.
Pneumatic interfaces for
VTSA pneumatics,
Midi/Maxi pneumatics
or CPA pneumatics From a technical point of view, the pneumatic interfaces
for VTSA pneumatics, Midi/Maxi pneumatics or CPA pneuĆ
matics represent electrical modules with a variable (configuĆ
rable) number of digital outputs for activating the integrated
valves.
Detailed information on the CPX pneumatic interfaces and
MPA pneumatic modules can be found in the manual for the
CPX I/O modules of type P. BE−CPX−EA−...
Valve terminal pneumatics
The valve terminal pneumatics provide the following:
ć Common channels for supply and exhaust air
ć Electric signals for all valve solenoid coils
Working lines 2 and 4 are provided for each valve position on
the individual pneumatic modules. The valves are supplied
with compressed air via the common channels or via special
supply modules. Both the air and auxiliary pilot air from the
valves are also exhausted via these common channels.
Further modules for pressure supply are also available,
e.g. in order to permit work to be carried out with different
work pressures.
