Input port INPUT directly links to each other with the output terminal of optocoupler O.
By driving circuit, realize the intellectuality in ecological room, guaranteeing under the prerequisite of practical safe reliability, be operate more convenient and intuitive.
The physical circuit of solenoid valve testing circuit of the present utility model is described below:
Operate as normal: switch ON/OFF is the switch of control electromagnetic valve L, when open electromagnetic valve L, and the voltage of 12V process resistance R 1, solenoid valve L, triode Q conducting over the ground, diode D conducting this moment.Electrothermal relay FR is given through resistance R 1 in another road, because diode D conducting, so electrothermal relay FR conducting.INPUT is changed to high level input port.
Fault: when solenoid valve went wrong, because diode D can't conducting impel optocoupler FR to end, then this moment, input port INPUT was changed to low level, and CPU judges that solenoid valve has fault, thereby closes the controllable silicon among the electrothermal relay FR.
The foregoing description just is to allow the one of ordinary skilled in the art can understand content of the present utility model and enforcement according to this for technical conceive of the present utility model and characteristics being described, its objective is, can not limit protection domain of the present utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the present utility model.
