to EU EMC Directive
– Emitted interference
1)
– Immunity to interference
2)
1) The MPA-S valve terminal is intended for use in an industrial environment. Outside of industrial environments, e.g. in commercial
and mixed-residential areas, actions to suppress interference may have to be taken.
2) The maximum signal cable length for the MPA-S valve terminal with multi-pin plug connection is 10 m

A.1.4 Electrical data
MPA-F v alve terminal with multi-pin plug conn ection:
– The maximum number of sub-bases that can be co nfigured corresponds to th e num-
ber of addresses available. The maximum number of solenoid coils which can be actu-
ated is limited by the multi-pin plug connection to 24 addresses.
MPA-S valve terminal with CPX terminal:
– A maximum of 16 sub-bases (MPA-S with electric supply plate) or 8 sub-bases (MPA-S
without electric supply plate) are permitted.
