2.1 The MPA-S valve terminal
Festo supports your automation tasks at machine level with the MPA-S valve terminal. The modular
structure of the MPA-S valve terminal enables you to match this valve terminal optimally to your ma-
chine or system.
The valve terminal pneumatics establish the following connection:
– Common ducts for supply and exhaust air
– Electric signals of all 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 (operating pressure and pilot pressure) via the common chan-
nels and connections in the basic components. The exhaust air (from the valves and the pilot exhaust
air) is also exhausted via these common channels. Further components for pressure supply are also
available, e.g. in order to supply pressure zones.
The MPA-S valve terminal is equipped with current reduction. The nominal current of the solenoid coils
is then reduced after the high-current phase (switching operation). The current reduction offers the
following advantages:
– The MPA-S valve terminal has a lower energy consumption
– The power unit for the voltage supply to the MPA-S valve terminal can be designed more economic-
ally depending on the individual case
– The solenoid coils have lower power loss and produce less waste heat.
