Directly replaces imported products of related models and has the following advantages:
■Low energy consumption (less than 15ma);
■1KHz---3KHz high-speed response;
■Automatic pin polarity protection, wiring errors will not damage the device itself;
■Pure copper silver-plated leads, long-term oxidation resistance, effectively ensuring system stability;
■Automatic load detection function, automatic protection and yellow light indication in case of short circuit or overload;
■Built-in amplifier and digital conversion circuit, unified output CMOS standard level, convenient signal collection, can be directly matched with a variety of loads;
■Action modes such as ON during light and ON during blackout can be switched by connecting the "L" terminal and the "+" terminal. This function can be used to easily form a suitable small control system;
