Valve terminals MPA-L
Key features – Electrical components
Electrical connection – Left-hand end plate
The electrical connection for
connecting the valves to a higher-level
controller is located in the left-hand
end plate.
The different connection options can
be easily switched by replacing the
left-hand end plate, while the
pneumatic connections remain as
they are.
The valves are switched by means of
positive or negative logic (PNP or
NPN). Mixed operation is not
permitted.
Guidelines on addressing for valves/solenoid coils
 The numbering of the addresses
goes from left to right in ascending
consecutive order. The following
applies to the individual valve
positions: address x for coil 14 and
address x+1 for coil 12.
 Each sub-base/electrical
interlinking module occupies a
defined number of addresses/pins:
– For single solenoid valve: 1
– For double solenoid valve: 2
– For combination of four
sub-bases for single solenoid
valves: 4
– For combination of four
sub-bases for double solenoid
valves: 8
-H- Note
If a single solenoid valve is
assembled on a double solenoid
valve position, the second address
(for coil 12) is also occupied and
cannot be used.
