Terminal CPX-P
Technical data – Pneumatic interface VMPA‐FB
Function
The pneumatic interface VMPA‐FB
establishes the electromechanical
connection between the CPX-P ter­
minal and the valve terminal MPA-S.
The signals from the bus node are for­
warded to the control electronics in
the electrical modules of the valve ter­
minal MPA-S via the integrated CPX-P
bus. The bus signal for activation of
the solenoid coils is converted in the
electronics module for max. 8 coils.
From a technical point of view, the
individual MPA pneumatic modules
each represent a separate electric
module with digital outputs. Valves,
which are galvanically isolated, can
be supplied with power via the
interlinking block CPX-GE-EV-V.
Applications
Interface to the valve terminal
MPA-S
Max. 128 solenoid coils
Features of the electronics module
of the valve terminal MPA-S can be
parameterised, for example status
of the solenoid coils in the event of
fieldbus communication being
interrupted (fail-safe), individual
channel diagnostics can be acti­
vated, condition monitoring can be
activated individually for each valve
The pneumatic interface receives
the voltage for the electronics and
the supply voltage for the valves
from the left-hand interlinking
block and feeds them through to
the electronics modules of the valve
terminal MPA-S
Electronics modules of the valve
terminal MPA-S:
– Undervoltage of valves
– Short circuit of valves
– Open load of valves
– Counter preset reached in
condition monitoring
