Patent ID: 6916192

Claim:
A control device comprising: a base, on which at least one component mounting area is provided, said base being equipped with a first electrical central interface connected with an internal electrical bus extending in the base, and at least one electrical connection module having electrical inputs or outputs permitting a temporary connection of electrical cables which lead away from the control device, said connection module being selectively mountable on the at least one component mounting area and having a second electrical central interface adapted to automatically make contact and, respectively, interrupt contact with the first electrical central interface upon mounting and removal of the electrical connection module; and at least one electrically controlled fluid control module selectively mountable instead of the electrical connection module on the at least one component mounting area of said base, said fluid control module including an electrical circuit board provided with a second electrical central interface adapted during mounting and removal of the fluid control module to automatically make contact and, respectively, interrupt contact with the first electrical interface of the base, the fluid control module furthermore having an internally mounted electrically operated valve means connected to said circuit board and fluid line connections accessible from the outside for the temporary connection of fluid lines coming from a pressure source and fluid lines leading to at least one load, said electrically operated valve means being adapted to control the connection between different ones of said fluid line connections based on control signals received from said internal bus.
