Valve terminals MPA-S
Key features
Individual connection
Valves can also be used on individual
sub-bases for actuators further away
from the valve terminal.
The electrical connection is estab
lished using a standard 4-pin M8 plug
(EN 60947-5-2).
Further information
èVMPA1
Multi-pin plug connection
The signal flow from the controller to
the valve terminal takes place via a
pre-assembled or self-assembled
multi-wire cable to the multi-pin plug
connection, which substantially
reduces installation time.
The valve terminal can be equipped
with max. 24 solenoid coils. This
corresponds to 4 to 24 MPA1 or 2 to
24 MPA2 valves, or a combination of
both.
Versions
Sub-D connection
Pre-assembled multi-pin cable
Multi-pin cable for self-assembly
AS-interface connection
A special feature of the AS-interface is
its ability to simultaneously transmit
data and supply power via a two-wire
cable. The encoded cable profile
prevents connection with incorrect
polarity.
The valve terminal with AS-interface is
available in the following versions:
With two to eight modular valve
positions (max. 8 solenoid coils).
This corresponds to 2 to 8 MPA1 or
2 to 8 MPA2 valves, or a
combination of both.
With all available valve functions.
The connection technology used for
the inputs can be selected as with
CPX: M8, M12, Harax, Sub-D,
Cage Clamp® (terminals to IP20).

Valve terminals with CP connection
are intended for connection to higher-

Key features
Fieldbus connection via the CPX system
An integrated fieldbus node manages
communication with a higher-order
PLC. This enables a space-saving
pneumatic and electronic solution.
Valve terminals with fieldbus inter
faces can be configured with up to
16 manifold blocks. In conjunction
with MPA1 and 8 solenoid coils per
manifold block, up to 128 solenoid
coils can thus be actuated. An MPA2
with 4 solenoid coils per manifold
block can actuate 64 solenoid coils.

Valve terminals MPA-S
Peripherals overview
Modular pneumatic components
The modular design of the MPA
facilitates maximum flexibility right
from the planning stage and offers
maximum ease of service in
operation.
The system consists of manifold
blocks and valves.
The manifold blocks are screwed
together and thus form the support
system for the valves.
They contain the connection ducts for
supplying compressed air to and vent
ing from the valve terminal as well as
the working lines for the pneumatic
drives for each valve.
Each manifold block is connected to
the next using three screws.
Individual terminal sections can be
isolated and further manifold blocks
inserted by loosening these screws.
This ensures that the valve terminal
can be rapidly and reliably extended.
Modular electrical peripherals
The manner in which the valves are
actuated differs according to whether
you are using a multi-pin terminal,
fieldbus terminal or individual valve.
The MPA with CPX interface is based
on the internal bus system of the CPX
and uses this serial communication
system for all solenoid coils and a
range of electrical input and output
functions.
Serial linking facilitates the following:
Transmission of switching
information
High valve density
Compact design
Position-based diagnostics
Separate voltage supply for valves
Flexible conversion without address
shifting
Transmission of status, parameter
and diagnostic data

Option of CP interface
CPX-CEC as stand-alone controller

server

Valve terminals MPA-S
Key features – Pneumatic components
Sub-base valve
MPA offers a comprehensive range of
valve functions. All valves are
equipped with patented sealing
system which facilitates efficient
sealing, a broad pressure range and
long service life. To increase power
they have a pneumatic pilot control
supplied by pilot air.
Sub-base valves can be quickly
replaced since the tubing connectors
remain on the manifold block.
This design is also particularly flat.
Irrespective of the valve function there
are sub-base valves with one solenoid
coil (single solenoid) or with two
solenoid coils (double solenoid or two
single solenoid valves in one
housing).
Constructional design
Valve replacement Extension
The valves are attached to the metal
manifold block using two screws,
which means that they can be easily
replaced. The mechanical sturdiness
of the manifold block guarantees
excellent long-term sealing.
Blanking plates can be replaced by
valves at a later date. The dimensions,
mounting points and existing pneu
matic installations remain unchanged
during this process.
The valve code (M, MS, MU, J, N, NS,
NU, K, KS, KU, H, HS, HU, B, G, E, X, W,
D, DS, I) is located on the front of the
valve beneath the manual override.
