Abstract
The utility model discloses an energy-saving double-coil magnetic latching relay device with a differential driving circuit, which comprises the components of: a differentiating circuit, a driving circuit and a double-coil magnetic latching relay. The differentiating circuit is composed of four local differentiating circuits. Each local differentiating circuit is obtained through connecting a capacitor and a resistor in series. The capacitor is an input end. The resistor is connected with the cathode of a power supply. A connecting node between the capacitor and the resistor is the output end of the local differentiating circuit. The driving circuit is composed of two triodes. The base electrode of each triode is connected with two output ends of the local differentiating circuits; the emitter electrode of each triode is connected with the cathode of the power supply; and the collector electrode of each triode is connected with two input ends of the double-coil magnetic latching relay. The other input ends of the relay are connected with the anode of the power supply. The energy-saving double-coil magnetic latching relay device is advantageous in that: the power of the relay is only generated at a rising edge period or a falling edge period; at other time, because end voltage is zero, the consumed power is zero; and therefore the energy-saving double-coil magnetic latching relay device has an excellent energy saving effect.
