  • all the first secondary electrical contacts 74a are connected to one of the primary contacts 73, and furthermore each one second secondary contacts 74b also connected to one of the primary contacts 73, respectively.
  • each ground contact 76 of the two secondary terminal units 56a, 56b and at least one ground contact 75 of the primary terminal unit via at least one internal ground conductor 77a, 77b.
  • the internal connection conductors 57a, 57b, as well as the internal ground conductors 77a, 77b, are expediently realized in the form of conductor tracks, which are formed on a carrier body formed, for example, as a circuit board.
  • a realization by means of flexible cables would also be conceivable.
  • each secondary connection unit 56a, 56b has a number of first and second secondary electrical contacts 74a, 74b, which corresponds to half the number of primary contacts 73 of the primary connection unit 52.
  • Each first secondary electrical contact 74a and each second secondary electrical contact 74b is connected to a primary contact of the primary connection unit 52 specifically assigned to it, so that each primary contact 73 is connected to only one secondary contact 74a or 74b.
  • first and second electrical actuating cables 58a, 58b can be connected to the two secondary connection units 56a, 56b.
  • a valve unit 27 only a first valve interface 47a only the electrical secondary contacts 74a of the first secondary connection unit 56a come to full application, while in the second secondary connection unit 56b the unneeded secondary contacts 74b remain unused.
  • each double-occupied primary contact 73 is connected both to a first secondary contact 74a of the first secondary connection unit 56a and to a second secondary contact 74b of the second secondary connection unit 56b.
  • the number of the first secondary contacts 74a is twice as large as that of the second secondary contacts 74b, so that half the number of existing first secondary contacts 74a is in each case contacted by a primary contact 73 which is simultaneously also connected to a second secondary contact 74b.
  • FIG. 7 thus opens up the possibility of equipping the valve arrangement 100 with a number of valve units 27 having in each case two valve interfaces 47a, 47b, which corresponds to half the number of primary contacts 73 present. In the embodiment, this is twelve pieces. Due to the double occupancy of a portion of the primary contacts 73, however, it is also possible in addition to each valve unit 27, which has only a first valve interface 47a, to install another such valve unit 27 equipped with only one first valve interface 47a. This additional valve unit 27 can then be connected to the first secondary contact 74a which is connected to the same primary contact as the second secondary contact 74b which, in the absence of a corresponding number of bistable valve units 27, is unused.
  • each bistable valve unit 27 equipped with two valve interfaces 47a, 47b two monostable valve units 27 equipped with only one valve interface 47a can be mounted, which can then be electrically actuated with full utilization of the existing number of primary electrical contacts 73.
  • valve units 27 will be placed in such a sequence that, beginning with the front of the valve group 32 facing the connection region 63, first the bistable valve units 27 and only then the monostable valve units 27 are arranged.
