Title:
SOLENOID VALVE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3174440
Kind Code:
B2
Abstract:
PURPOSE: To provide a solenoid valve control device wherein wiring is saved in a detecting switch set up in a liquid pressure actuator so that operation of a solenoid valve can be well detected.
CONSTITUTION: A device has a main controller 9 for transmitting in a series signal a data of 1 bite unit for driving a plurality of solenoid valves 1A to 1H provided in a manifold 2 and a subcontroller 8 for driving the solenoid valve by receiving this data, to provide detection switches 7A to 7D for detecting the operating condition in liquid pressure actuators 4A to 4D actuated by driving the solenoid valves 1A to 1H, and a communication controller for receiving a detection signal, detected by the detection switches 7A to 7D by respectively selecting a plurality of the detection switches 7A to 7D, is provided in the subcontroller 8. Further, a plurality of the detection switches 7A to 7D and the communication controller are connected in parallel by communication lines 42, 43.
