## Abstract

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.

## Claims

### Claim 1

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:
said switch unit is equipped with a plurality of manual switches to match each of the solenoid valves, and said manual switches can be switched over to a switching position to connect the solenoid valves to output terminals of the serial unit and to a switching position to connect the solenoid valves to power terminals.

### Claim 2 (depends on 1)

A solenoid valve controller according to claim 1, wherein said solenoid valves, said switch unit and said serial unit are intensively installed on a common mounting member.

### Claim 3 (depends on 1, 2)

A solenoid valve controller according to claims 1 or 2, wherein each of the manual switches of the switch unit has a sub-switch to be turned on and off in response to manual operation, and these sub-switches are connected in series between detection terminals for detecting switching condition of the manual switches.

### Claim 4 (depends on 1, 2)

A solenoid valve controller according to one of claims 1 or 2, wherein the switch unit is removably installed, and the solenoid valves and the serial unit can be directly connected by removing the switch unit.

### Claim 5 (depends on 3)

A solenoid valve controller according to claim 3, wherein the switch unit is removably installed, and the solenoid valves and the serial unit can be directly connected by removing the switch unit.
