1.1 Summary of variants
Festo can assist you with your automation problems at
the machine level by means of valve terminals. The
modular structure of the CP system enables you to in-
corporate the CP valve terminals and I/O modules to
best advantage in your machine or system.
Due to its compact structure, the CP valve terminal can
be mounted near to the actuators which it is to control.
This means that shorter compressed air tubing can be
used. Loss of air is therefore minimized and the time
required for pressurizing and exhausting the pressure
tubing is reduced. This is made possible by the use of
very compact valves with high flow which help to redu-
ce costs.

The CP valve terminals are available with the following
electrical connections:
Valve terminal
variants
IC connection CP connection
MP connection AS-i connection
Fig. 1/1: Variants of the CP valve terminal
The CP terminal with single connection is available with
2 to 8 valve plates (also in uneven spacing). The
electrical connection on this type of terminal is made
separately by means of a socket on each solenoid coil.
CP terminal
with
IC connection
This CP terminal is available with 4, 6 or 8 valve loca-
tions. The electrical connection of the solenoid coils is
made centrally via the multiple connector plate.
CP terminal
with
MP connection
The CP terminal with CP connector is available with 4,
6 and 8 valve plates. Connection to the higher-order
fieldbus node is made by means of a special CP cable.

This CP terminal is connected to the AS-i bus by me-
ans of a special AS-i cable. It is available with three
types of electrical connections:
CP terminal
with AS-i
connection – with additional supply connection for implementing an
emergency stop function
– with additional supply connection and 4 inputs (not
CPV18)
– without additional supply connection.
The CP valve terminals with AS-i connection can be fit-
ted with the following valve plates:
– two or four valve plates with 5/2-way single solenoid
valves
– two valve plates with 5/2-way doubkle solenoid
valves
– 2 valve plates each with 3/2-way single solenoid
valves
– Only CPV18: two valve plates with 5/3-way valves
blocked in mid-position.
PLEASE NOTE
The CP valve terminal with AS-i connection and 4 in-
puts is always with fitted 4 valve locations. Depen-
ding on the equipment fitted, these CP valve termi-
nals are filled, where necessary, with 1 or 2 reserve
plates.

CPV... 9802 1-5

The CP terminals are available in the following sizes:Grid sizes of
the CP terminals
Designation Valve plate Valve
CPV10 10 mm Micro valves
CPV14 14 mm Mini valves
CPV18 18 mm Midi valves
Mixed operation with both grid sizes on one CP termi-
nal is not permitted.
You can divide the CP valve terminal into two pressure
zones with the aid of the isolating plate. The isolating
plate is available in two variants:
Isolating plate
– Isolating plate with blocked compressed air channels
(1 and 11)
– Only CPV14: isolating plate with blocked exhaust
channels (3/5) and blocked compressed air channels
(1 and 11)
The CP valve terminal with CP connection can be fitted
with relay plates. Each relay plate contains two relays
for controlling two electrically-isolated outputs.
