Valve terminals MPA-L
Peripherals overview
Modular pneumatic components
The modular design of the MPA-L
facilitates maximum flexibility right
from the planning stage and offers
maximum ease of servicing during
operation.
The system consists of sub-bases and
valves.
The sub-bases form the support
system for the valves.
They contain the connection ducts for
supplying compressed air to and
venting from the valve terminal as
well as the working lines for the
pneumatic drives for each valve.
The sub-bases are joined together via
a tie rod system. This consists of a
threaded rod, threaded sleeve and
screw. The threaded rod/sleeve
combination is selected as
appropriate to the chosen number of
individual sub-bases.
A valve terminal can be easily
extended by adding individual
sub-bases or supply modules. This is
done by inserting suitable tie rod
extenders between the threaded rod
and sleeve.
This ensures that the valve terminal
can be rapidly and reliably extended.
-H- Note
The tie rod system for the valve
terminal MPA-L consists of at least
four sub-bases or two sub-bases
and one supply module.
Shorter valve terminals with two or
more valve positions can be
constructed without a sleeve.
Modular electrical peripherals
The mechanical connection between
the CPX modules is established using
tie rods. Two screws in the end plates
are all that are needed to assemble
the entire unit.
The tie rod ensures that the unit
resists high mechanical loads and is
therefore the "mechanical backbone"
of the CPX terminal.
The open design allows interlinking
blocks to be replaced in assembled
state.
The tie rod extension kit allows an
extra module to be added to the CPX
terminal.
The input/output modules,
connection blocks, fieldbus nodes or
control block of the CPX system are
mounted on the interlinking blocks
using four screws and can be almost
infinitely replaced or modified.
