Valve islands for centralized applications
Depending upon the machine confi guration and design, all
of the pneumatic actuators may be controlled form a
centralized control panel complete with all the necessary
pneumatic valves. The control valves would normally be
grouped together into a 'valve island' enabling the solenoids
to be eclectically interconnected and in turn linked to a PLC
via an industrial network. In this confi guration all the
solenoids can be connected to either remote devices
POSTTTIONed around the machine or back to the centralized
panel and signals transmitted to the PLC via the valve island
and industrial network. Other digital or analogue I/O can be
connected if required。
