The present invention provides a solenoid valve controller with simple arrangement, by which it is possible to easily check connecting conditions and operating conditions of solenoid valves. Between a plurality of solenoid valves 11 intensively installed and a serial unit 2 for performing on-off control of each of the solenoid valves according to a control signal from the controller, a switch unit 3 having a plurality of manual switches 30a to 30n to match each of the solenoid valves 11 is connected, and it is designed that each of the manual switches can be switched over to a first switching position to connect the solenoid valves 11 to output terminals 21a to 21n of the serial unit and to a second switching position to connect the solenoid valves to power terminals 20a and 20b.
A solenoid valve controller, comprising a plurality of solenoid valves intensively installed for controlling pressure fluid, a serial unit for performing on-off control of each of said solenoid valves according to a control signal from the controller, and a switch unit electrically connected between said solenoid valves and said serial unit, whereby:
