Central supply of compressed air to pneumatic modules
There is no pneumatic connection between several pneumatic modules of the
ET 200X. This means that you must supply compressed air to each pneumatic
module separately.
In order to feed the pneumatic modules centrally with air all the same, there is a
simple solution. You interconnect the compressed air lines by means of T plug
connections – for example, type QST-10-8 from FESTO, as basically shown in the
figure below.

Note
The rate of air flow is lower when T plug connections are used.

Note
Please note that the permissible operating pressure is reached before the valve is
switched electrically.
FESTO valve island for ET 200X
The pneumatic interface modules are expansion modules for connecting two
Regular FESTO valve islands:
S EM 148-P DO 16
S EM 148-P DO 16
You can obtain valve islands from FESTO. The valve islands are described in
separate documents.
