を特徴とする電磁弁開閉用ソレノイド駆動回路。 In a solenoid drive circuit for opening and closing a solenoid valve, the electromagnetic solenoid is supplied with a valve opening current for opening the valve and a holding current for continuously maintaining the valve open state. Two switching means are connected in series and connected in parallel to each other, and the switching means are respectively closed at the control timing of the valve opening current and the holding current so that the valve opening current and the holding current flow independently. A solenoid drive for opening/closing an electromagnetic valve, characterized in that it is provided with a closing means for detecting a current value flowing through the electromagnetic solenoid and a determining means for detecting a current value flowing through the electromagnetic solenoid and determining whether or not the detected current value is an excessive current value. circuit.
