ABSTRACT:
An apparatus for controlling a plurality of electromagnetic valves of manifold type including a parallel-in/serial-out unit for convert parallel control signals for a plurality of electromagnetic valves into a serial control signal and generating a composite control signal including the serial data signal, a start synchronous signal synchronized with the serial data signal and a driving voltage, a synchronous signal receiving circuit arranged on a manifold for generating a start signal in response to the control start synchronous signal supplied from the parallel-in/serial-out unit, a plurality of driver circuits each arranged on respective electromagnetic valves, a first driver circuit receiving said start signal supplied from said synchronous signal receiving circuit to convert the serial control signal into parallel control signals for driving the relevant electromagnetic valves and after driving the electromagnetic valves, said driver circuit producing an end signal, a synchronous signal transmitting circuit arranged on said manifold, the synchronous signal transmitting circuit receiving said end signal and supplying the synchronous signal, and three wires for transmitting the composite signal, start signal, end signal and synchronous signal among the parallel-in/serial-out unit, synchronous signal receiving circuit and synchronous signal transmitting circuit.
