CPX I/O modules
Processing signals can be evaluated with the CPX I/O mod
ules. Input modules provide inputs for connecting sensors
and enable cylinder positions to be scanned, for example.
Output modules provide universally usable electric outputs
for controlling low−current consuming devices (further valves,
bulbs, etc.).
Note
Including the CPX bus node, a maximum of10 electric CPX
modules plus a pneumatic interface are permitted on the
electric side.
The CPX I/O modules have various types of connections. The
connections are on a sub−base which can be removed from
the module. This offers the following advantages:
 The CPX terminal can be
fitted with the desired con
nections. It can be adapted easily to various applica
tions and operating conditions.
 When servicing is required, the electronics of the I/O
modules can be replaced without the need to dis
mantle the CPX terminal, or to loosen individual con
nections on the I/O modules.
The following types of
connection can be used:
 M12 connection, 5− or 8−pin
M8 connection, 3− or 4−pin
 Terminal strips, 16−pin
 Sub−D connection, 25−pin
 HARAX connection, 4−pin
