MPA-S valve terminal with multi-pin plug connection
The valve terminals can be configured with as many sub-bases as there are addresses available
( Tab. 5.9). With these valve terminals, the maximum number of solenoid coils which can be actuated
by the multi-pin plug connection is limited to 24 addresses.
If equipped exclusively with one 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:
MPA-S valve terminal Valve positions per
sub-base (n
