A modular electrical bus system has a grounding circuit through a plurality of modular units with each unit being both electrically and mechanically connectable together via a bridge member connecting adjacent units and the main communication module. The bridge member and modular units are grounded together with a ground circuit that extends within both components.

Modular electrical bus system with built in ground circuit

A plurality of solenoid control valves each mounted on a module of a manifold with a terminal block for each valve removably received in the manifold and having at least three terminals. A printed circuit board with a microprocessor and a coil driver mounted on the board has three spaced apart electric connectors releasably secured to separate terminals of the same terminal block and each having a shank received in a hole through the circuit board and electrically connected to a printed circuit on the board by solder to both mount and support the circuit board on the terminal block and provide output of the coil driver to the coils of two solenoids for controlling the application of electric power to them. An auxiliary circuit board with another coil driver and electric connectors mounted on another terminal block is daisy chained with the microprocessor for controlling the application of electric power to additional solenoid coils. Additional solenoid coils may also be connected to the outputs of the coil drivers for controlling through the microprocessor the application of electric power to them.
