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 (operating pressure and pilot
pressure) via the common channels and connections in the
basic components. The exhaust air (from the valves and the
pilot exhaust air) is also exhausted via these common chan
nels. Further modules for pressure supply are also available,
e.g. in order to supply pressure zones.
The MPA valve terminal is provided with current reduction.
The rated current of the valve solenoid coils is then reduced
after the high−current phase (switching procedure). The cur
rent 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
