1.1 Summary of variants

Festo supports your automation task at the machine

level with CPA valve terminals. The modular structure of

the CP system enables you to optimally integrate the

CPA valve terminals and I/O modules in your machine

or system.

Due to its compact structure, the CPA valve terminal

can be fitted very closely to the actuators to be control-

led. As a result, shorter compressed air tubing can be

used. Flow losses are thereby minimized and the time

required for pressurizing and exhausting the com-

pressed air tubing is reduced. This is made possible by

the use of very compact valves with sufficient flow,

thereby reducing costs.

This CPA valve terminal is available with 2 to max. 22

single solenoid valves or 11 double solenoid valve loca-

tions. Max. 22 valve coils can be controlled. The electri-

cal connection for the valve solenoid coils is made cen-

trally via the multipin plug.

CPA valve ter-

minal with

MP con-

nection

The CPA valve terminal with CP connection is available

with 2 to max. 16 single solenoid valves or max. 8

double solenoid valve locations. Max. 16 valve coils can

be controlled. The connection to the higher-order field

bus node is made via a special ready-to-use CP cable.

CPA valve ter-

minal with

CP con-

nection

This CPA valve terminal is connected to the AS-i bus by

means of a special AS-i cable. It is available with two

types of electrical connections:

CPA valve ter-

minal with

AS-i con-

nection – with additional supply connection (load voltage can

be switched off separately)

– without additional supply connections

Both variants are available with 2 to max. 4 single sole-

noid valve locations or max. 2 double solenoid valve

locations. Max. 4 valve coils can be controlled.

All CPA valve terminal variants are available with micro

valves (width of valve 10 mm, CPV10) or with mini

valves (width of valve 14 mm, CPV14). Mixed fitting

with both types of grid dimensions is not possible on a

CPA valve terminal.
