1.1 The MPA-S valve terminal
Festo supports your automation tasks at machine level with
theMPA-Svalveterminal.Themodularstructureofthe
MPA-S valve terminal enables you to match this valve
terminal optimally to your machine or system.
The valve terminal pneumatics establish the following
connections:
– Common ducts for supply and exhaust air
– Electric signals from 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 channels 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 economically depending
on the individual case
– The solenoid coils have less power loss and produce less
waste heat
