<p>PURPOSE: To provide a solenoid valve control device of simple constitution capable of easily checking the connected state, operation state or the like of a solenoid valve. CONSTITUTION: A switch unit 3 with a plurality of manual switches 30a to 30n is connected between a plurality of solenoid valves 11 centrally laid and a serial unit 2 to control each of the solenoid valves 11 for on-off operation according to a control signal from a controller, with the switches 30a to 30n kept corresponding to each of the valves 11. Furthermore, each of the switches 30a to 30n is made selectable between the first selecting position for connecting the valves 11 to output terminals 21a to 21n of the unit 2, and the second selecting position for the connection thereof to power supply terminals 20a and 20b.</p> |
