1.1 The MPA valve terminal
Festo assists you in solving your automation tasks at machine
level with MPA valve terminals. The modular structure of the
MPA valve terminal enables you to use this valve terminal
optimally in your machine or system.
The valve terminal pneumatics provide the following:
 the common channels for supply and exhaust air
 the electric signals from all valve solenoid coils
Work connections 2 and 4 are provided for each valve loca
tion on the individual pneumatic modules. The valves are
supplied with compressed air via the common channels and
connections in the basic components. Both the exhaust air
and pilot exhaust air from the valves are also exhausted via
these common channels. Further modules for pressure sup
ply are also available, e.g. in order to supply pressure zones.
The MPA valve terminal is fitted with current reduction. The
rated current of the valve solenoid coils is then reduced after
the high−current phase (switching procedure). The current
reduction offers the following advantages:
 the MPA valve terminal has a lower energy consumption
 the power unit for the voltage supply to the MPA valve
terminal can be designed more economically depending
on the individual case
 the valve solenoid coils have less leakage power and pro
duce less waste heat
