1.1 The valve terminal MPA−L
Festo supports your automation tasks at machine level with
the valve terminal MPA−L. The modular structure of the valve
terminal MPA−L enables you to match this valve terminal opti
mally to your machine or system.
The valve terminal MPA−L provides 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 sub−bases. The valves are sup
plied with compressed air (operating pressure and pilot pres
sure) 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 compressed air supply are also avail
able, e.g. in order to supply pressure zones.
The valve terminal MPA−L is equipped with current reduction.
The nominal current of the solenoid coils is then reduced
after the high−current phase (switching procedure). The cur
rent reduction offers the following advantages:
The valve terminal MPA−L has a lower power consumption
The power unit for the voltage supply to the valve ter
minal MPA−L can be designed more economically depend
ing on the individual case
The solenoid coils have less leakage power and produce
less waste heat
