Beschreibung
Zusammenfassung:	The utility model relates to a two-wire electronic valve in-position automatic detection circuit, which comprises a microcomputer controller, a valve and an in-position detection control unit. The in-position detection control unit comprises a current limiting resistor, an optical coupler and a divider resistor, wherein the valve is serially connected with the current limiting resistor to be connected with the input of the optical coupler, the output of the optical coupler is connected with the microcomputer, and the divider resistor is parallel connected with three resistors to be connected with the input of the optical coupler. The utility model adopts a two-wire electronic in-position detection method, having simple structure and high reliability, which can confirm reliable in-position switch of valves, reduce unnecessary electricity waste of battery and improve the service life of battery.
