Structure and function of the modules
7.4. pneumatic base module
general description 7.4.1.
The pneumatic base module features the working connections for the following applications. Several modules can
be placed in rows by connecting them. The seal on the outside is retained. The P-connection can be sealed by using
a bulkhead. This allows movement in one valve block with different operating pressures.
Variants
The variant versions differ in add-on dimension, number of valve locations, wiring diagram of the valves, version of the
working connections and optional use of non-return valves Not all conceivable variants have been implemented.

add-on dimension
Larger valves also require wider base modules. This allows a higher flow rate to be implemented. Currently the fol-
lowing add-on dimensions are available:

number of valve locations per module
As module optimization is based on low granularity, cost savings, structure of valve discs and utilization of the elec-
tronics, it is useful to have modules with a varying number of valve locations.
type of working connections
Whether quick plug-in connections or thread - you as the customer decide which is the optimum variant for you.
