Solenoid valve drive control device

Abstract

Abstract PURPOSE:To sharply reduce a wiring amount by a method wherein a plurality of solenoid valves are intercoupled through a common bus line, a CPU and an internal memory are disposed to a unit on the manifold side, and a solenoid valve is turned ON and OFF by means of an address signal and a data signal fed through a common buss line and related to an individual solenoid valve. CONSTITUTION:Address signals form a plurality of solenoid valves and an individual solenoid valve and a solenoid valve current are fed to a buss line 10. A unit 21 on the manifold side having a CPU 24 and an internal memory 26 specifies a given solenoid valve unit 20 by means of an address signal fed to the bus line 10, and by means of a data signal from the specified solenoid valve unit 20, the solenoid of the solenoid valve is energized or deenergized.
