Fig. 1/3: Pneumatic supply plate
The pneumatic supply plate can also be used for additional
power supplies. These are, for example, necessary in the case
of valve terminals operated with several pressure zones or
when a large number of valves on the valve terminal are
switched simultaneously to flow.
The pilot control of the solenoid coils is supplied with internal
or external pilot air. This pilot air is made available for the
complete valve terminal (also via the pressure zones) via the
right−hand end plate (see Tab. 1/4).
A selector plate on the right−hand end plate makes it possible
to branch the pilot air internally from the supply port (1) or to
take it from the separate supply via the port (12/14).
Note
Internal pilot air supply is only permitted if the operating
pressure of the last pressure zone (at the right−hand end
plate) is between 3 and 8 bar .
