The invention relates to an energy-saving magnetic latching relay circuit. A direct impulse is applied on a relay coil at the moment when the relay is powered up to drive the relay to be converted; and a reverse impulse is applied on the relay coil when the input end is powered down to drive the relay to be restored. After being connected with each other in series, a resistor R1 and a resistor R2 are connected between the positive electrode and the negative electrode of a power supply, and a connecting point of the R1 and the R2 is connected to the base electrode of a triode V3; after passing through a diode V1, the positive electrode of the power supply is respectively connected to the positive electrode of a capacitor C1, the positive electrode of a thyristor V2 and one end of a resistor R3; the negative electrode of the capacitor C1 is connected to one end of the magnetic latching relay coil, and the other end of the relay coil is connected to the negative electrode of the power supply; the control electrode of the thyristor V2 is connected to the collector electrode of the triode V3; and the other end of the resistor R3 is also connected to the collector electrode of the triode simultaneously. The energy-saving magnetic latching relay circuit is high-efficient and energy-saving, thus being beneficial to environmental protection; the relay magnetic coil has low power consumption and long service life; and the structure is simple and the cost is low.
Description
technical field [0001] The invention relates to a relay, in particular to an energy-saving magnetic latching relay circuit, which belongs to the technical field of electromagnetic relays. Background technique [0002] After the conventional electromagnetic relay is powered on and converted, in order to maintain the working state of the relay, a continuous current must pass through the coil, resulting in unnecessary waste of resources. The magnetic latching relay relies on the magnetic steel inside the product to maintain the contact state after the relay is switched, basically consuming no energy. For the traditional single-coil magnetic latching relay, it is very troublesome to use it by reversing the polarity of the input terminal to realize the switching of the relay. Contents of the invention [0003] The object of the present invention is to provide a simple, low-cost, and low-power electromagnetic relay circuit for the disadvantages of conventional electromagnetic r...
