Terminal CPX-P
Key features
Variants for controlling the CPX-P terminal (with bus node, without preprocessing)
Bus node
Different bus nodes are used to
integrate the terminal in the control
systems of various manufacturers.
The CPX-P terminal can therefore be
operated on commonly used fieldbus
systems:
PROFIBUS DP
PROFINET
DeviceNet
Integration in universal networks
based on Ethernet opens up new
possibilities. Faster data transmis
sion, real-time capability and above
all additional IT services such as file
transfer, web server, web monitor as
integrated website in the CPX-P
terminal, text message/e-mail alerts,
etc. open up a wide range of
synergies.
These include standardised and
universal communication technology
across all areas, including operating
level, management level and field
level in the production environment,
with protection to IP65.
The following protocols are supported:
EtherNet/IP
Modbus/TCP
PROFINET
Bus node Industrial Ethernet bus node
PLC
Fieldbus
Web
IT services:
E-mail
File transfer
PLC
Industrial Ethernet
Communication with higher-order
controller via fieldbus
No preprocessing
Fieldbus protocol dependent on
CPX bus node used
Up to 90 I/Os, depending on the
bus node used
Connection to a higher-order
controller directly via EtherNet/IP,
Modbus/TCP or PROFINET
No preprocessing
Monitoring via Ethernet and web
applications
Up to 300 I/Os
-H- Note
Every electrical connection can be
combined with an appropriate
number of I/O modules and/or
pneumatic components, depending
on its address capacity.
Likewise, every pneumatic variant of
the CPX-P terminal can be operated
with every electrical connection
variant.

Terminal CPX-P
Key features
Connection of inputs and outputs to the CPX-P terminal
Digital and analogue CPX I/O modules Electrical connection
The connection technology for
sensors and additional actuators
offers a wide range of digital and
analogue input and output modules
and is freely selectable – as
appropriate to your standard or
application.
The input/output modules can be
combined as required with the
connection blocks:
M12, 5-pin
M12, 5-pin, with quick lock and
metal thread
M8, 3-pin
M8, 4-pin
Sub-D, 25-pin
Harax®, 4-pin
CageClamp®
(with cover also to IP65/67)
Screw terminal and spring-loaded

CPX modules for NAMUR sensors Electrical connection
The electronics modules for NAMUR
sensors can only be combined with
certain connection blocks.
The input modules can be combined
as required with the connection
blocks:
M12, 4-pin

4CPX input module for NAMUR
sensors, non-intrinsically safe
design
5CPX input module for NAMUR
sensors, intrinsically safe
design
6Actuator/machine component
with NAMUR sensors
CPX-P modules are suitable for con
figuring intrinsically safe or non-in
trinsically safe circuits depending
on the design selected.
This enables components from both
safe and hazardous zones to be
connected to the CPX-P terminal.
The components for the intrinsically
safe zone are marked in blue or
entirely coloured blue to distinguish
them visually.
-H- Note
Intrinsically safe circuits are circuits
which release so little energy during
operation, or in the event of certain
faults under specified test condi
tions, that no ignition can occur in a
particular potentially explosive
atmosphere.

Terminal CPX-P
Key features
Pneumatic variants of the CPX-P terminal
With valve terminal MPA-S – centralised
The electrical CPX-P terminal is a
modular peripheral system for valve
terminals.
The system is specifically designed
so that the valve terminal can be
adapted to suit different
applications.
The modular system design lets you
configure the number of valves,
inputs and additional outputs to
suit the application.
Ordering
The CPX-P terminal with valve
terminal is fully assembled according
to your order specifications and
individually tested. The finished valve
terminal consists of the electrical
peripherals including the desired
actuation and the selected
components from the MPA-S modular
system.
The CPX-P terminal with valve ter
minal is ordered using two separate
order codes. One order code defines
the electrical peripherals type CPX-P,
while the other specifies the
pneumatic components of the valve
terminal.
The electrical peripherals type CPX-P
can also be configured without a
valve terminal and can be used on a
fieldbus. For this order, only the order
code for the electrical peripherals is
required.
The order lists for the pneumatic
components can be found on
èInternet: mpa-s
(valve terminal MPA-S)

Hood
Description è98
The CPX hood CAFC is a space and
cost-saving alternative to a control
cabinet.
It is designed as an extruded
aluminium profile and is installed on
a mounting plate.
The valve terminal is well protected
and is quick to install without the
need for complex control cabinet
installation for cables and tubing.
The rail and the two mounting brack
ets are mounted on a back plate. The
hood is attached to the retaining rail
and secured with two screws. There is
also a stand-by position (locking of
the hood in the open position).
The hood is locked using two side
screws (which meet the requirements
for a special lock in compliance with
ATEX).
The CPX hood can be ordered online
using the valve terminal configurator.
Advantages of the CPX hood Points to note when using the CPX hood
Impact protection (min. 7 J) for the
underlying modules in combination
with a suitable mounting plate
provided by the user
Protection against electrostatic
discharge through the use of
electrically conductive materials
and the option of connecting an
earth wire
Protection against disconnection of
live plug connectors (by securing
the hood with at least one special
lock to EN 600079-0, 9.2 and 20)
UV protection for the underlying
CPX-P and MPA modules
CPX-P power supply via angled
plugs, no T-plugs
Electrical supply plate/additional
power supply only possible with
angled plug
No MPA vertical stacking
Use of larger QS fittings (for tubing
O.D. larger than 12 mm) only
possible with the angled design
Ducted exhaust air only with elbow
connector
The permissible ambient tempera
ture of the valve terminal is reduced
by 5 °C
-H- Note
The CPX hood has no influence on
the ATEX classification of the valve
terminal or of the CPX terminal.
The CPX hood has no influence on
the IP protection class of the valve
terminal or of the CPX terminal.
The CPX hood does not protect
against the effects of the weather in
installations that are not in closed
spaces.

of length
Mounting rail: approx. 550 g per
1,000 mm of length

Plug coding
The connection blocks
CPX-P-AB-2XKL-8POL,
CPX-P-AB-2XKL-8POL-8DE-N-IS and
the sockets NECU-L3G8 can be
matched to one another using the
coding elements CPX-P-KDS-AB-2XKL.
This reduces the likelihood of a socket
being inserted in the wrong slot after
it is removed from the CPX-P terminal
(protection against incorrect
insertion).

Terminal CPX-P
Key features – Assembly
Mounting options
Valve terminals with CPX-P terminal
support different mounting options
for direct machine mounting with high
protection and control cabinet
installation.
H-rail mounting
A
B
The rear profile of the CPX-P interlink
ing block has a preformed H-rail
mounting so that the CPX-P terminal
can be attached to the H-rail using the
H-rail mounting kit.
The CPX-P terminal is mounted on the
H-rail (see arrow A) and
then swivelled onto the H-rail and
secured in place with the clamping
component (see arrow B).
The optional earthing plate enables a
connection to be established to the
machine potential/earth in one easy
step.
For H-rail mounting you will need the
following mounting kit:
CPX-CPA-BG-NRH
This facilitates mounting of the CPX-P
terminal on H-rails to EN 60715.
An additional mounting kit is required
for combination with valve terminals.
Wall mounting
The end plates of the CPX-P
terminal, the valve terminal and the
pneumatic interface include
mounting holes for wall mounting.
Additional mountings for the CPX-P
terminal are available for longer
valve terminals.
Additional mounting components
Additional mounting brackets for the
CPX-P terminal that can be screwed
onto the interlinking blocks are
available for longer valve terminals.
-H- Note
For CPX-P terminals with 4 or more
interlinking blocks: you will require
additional mounting brackets of the
type CPX-M-BG-RW approx. every 100
or 150 mm. These are supplied pre-
assembled.
Linking with screws
The mechanical connection between
the CPX-P modules is created using
special angle fittings.
The CPX-P terminal can thus be
expanded at any time.
