MPA valve terminal with MP or MPM connection
The valve terminals can be configured with as many sub−
bases as there are addresses available (see table). With these
valve terminals, the maximum number of solenoid coils which
can be actuated by the multipin connection is limited to 24
addresses.
If control is carried out with size MPA 1 or MPA 2 and valves
with the same number of solenoid coils, this will result in the
following maximum number of sub−bases:
