1.1 The VTSA... valve terminal
Festo assists you in solving your automation tasks at machine
level with VTSA... valve terminals. The modular structure of
the valve terminal enables you to match it optimally in your
machine or system.
The valve terminal pneumatics provide the following:
 the common channels for supply and exhaust air
 the electric signals from all valve solenoid coils
Work connections 2 and 4 are provided for each valve loca
tion on the individual manifold sub−bases. The valves are
supplied with compressed air (operating pressure and pilot
pressure) via the common channels and connections in the
pneumatic supply plates. The exhaust air (from the valves
and the pilot exhaust) is also exhausted via these common
channels and connections.
The valve terminal can be fitted with further pneumatic sup
ply plates, e.g. in order to supply pressure zones.
The scope of functions at each valve location can be extended
by means of additional vertical stacking components, e.g.
exhaust restriction or pressure regulation.
Sizes of the VTSA... valve
terminal
The valve terminals are available with valves of sizes 18mm,
26mm (as per ISO 15407−2) and size ISO 1 (size 42 mm) (as
per ISO 5599−2). An adapter plate is not required if you wish
to combine these three sizes on the valve terminal.
1.1.1 Overview of variants
The VTSA... valve terminal is available with the following elec
trical connnection variants:
