Abstract
A modular fluid control module having a plug-in connector is provided for control of one or more functional load devices in response to fluid condition and demand input signals. The module includes a fluid circuit board having top and bottom plate members bonded to a common center plate. The top and bottom plates each have a plurality of parallel flow lines. The first and second parallel lines are substantially perpendicularly related to define an X-Y coordinate grid. The center plate has openings establishing preselected connection of the parallel flow lines in the top and bottom plates. The top plate includes a multiple input/output port connector which includes a plurality of ports connected to the parallel flow lines of the top plate. Each of the top and bottom plates includes a plurality of plug-in logic and control ports connected to select internal flow lines of the corresponding plate. A plurality of logic devices and interrelated control devices, such as fluid transmitters, fluid repeaters, fluid comparators, fluid signal receiving devices, fluid diodes and other similar devices, are coupled to the control ports for establishing selected response to the input signals and establishing output signals for the load devices to said port connector. The control ports not connected to a control device or other port is sealed by a cap or vented to atmosphere.
