    Circuit arrangements for the control of a bistable relay having a capacitor connected in series with its excitation winding, in which the series connection of coil and capacitor is connected to excitation voltage for the excitation of the relay and simultaneous charging of the capacitor, and, upon absence of excitation voltage, is short-circuitable through a semiconductor switch having its output circuit parallel-connected with the series connection of coil and capacitor, whereby the relay switches back to its starting position.

    The invention relates to switching equipment.
    A device for controlling a bistable relay, comprising three transistors connected in series with a coil and a power source, and a capacitor [1].
    The closest to the proposed technical essence and the achieved result is a device for controlling a bistable electromagnetic relay containing a capacitor and a diode connected in series with the relay coil and switch to a power source, a transistor, an emitter-collector junction of which is connected in parallel with the coil and capacitor, and a resistor [ 2].
    A disadvantage of the known devices is complexity.
    The purpose of the invention is simplification.
    This goal is achieved by the fact that the base-emitter junction of the transistor 25 is connected parallel to the diode, and the resistor is connected between the base and the collector.
    The drawing shows a diagram of the proposed device. thirty
    When the switch 1 is turned on, the charge current of the capacitor 3 flows through the coil 2 of the electromagnetic relay and the relay operates. The voltage drop across the diode 4 locks the base-emitter junction of the transistor 5, while limiting the voltage across it to the direct branch of the current-voltage characteristic of the diode.
    When the switch 1 is turned off, the discharge current of the capacitor 3, flowing through the relay coil, the base-emitter junction of the transistor 5 and the slave. torus 6, opens the transistor 5, after which it flows through its emitter collector junction and causes the relay to return.
    Thus, the relay returns by disconnecting the power source, which simplifies the control device. Diode 7 serves to protect the circuit from being connected to a power source with the wrong polarity.

    This invention relates to switching equipment. A device for controlling a bistable relay containing three transistors connected in series with a coil and a power source and a capacitor Ij is known. The device for controlling a bistable electromagnetic relay containing a capacitor and a diode connected in series is the closest result. with a relay coil and a switch to a power source, an emitter-collector junction transistor of which is connected in parallel to the coil and capacitor, and a resistor 2. A disadvantage of the known devices is complexity. The purpose of the invention is simplification. This goal is achieved by the fact that the base-emitter junction of the transistor is connected parallel to the diode, and the resistor is connected between the base and the collector. The drawing shows a diagram of the proposed device. When the switch 1 is turned on, the charging current of the capacitor 3 flows through the coil 2 of the electromagnetic relay and the relay is activated. The voltage drop across diode 4 closes the base-emitter junction of transistor 5, while simultaneously limiting the voltage across it to the direct branch of the current-voltage characteristic of the diode. When the switch 1 is disconnected, the discharge current of the capacitor 3 flowing through the relay coil is the base-emitter junction of transistor 5 and resis. torus 6, opens the transistor 5, then flows through its emitter-collector junction and leads to the return of the relay. Thus, the relay is reset by disconnecting the power source, which simplifies the control device. Diode 7 serves to protect the circuit from being connected to a power source with incorrect polarity. Claims An apparatus for controlling a bistable electromagnetic relay comprising a capacitor and a diode connected in series with a relay coil and switch to a power source, a transistor whose emitter-collector junction is impacted parallel to the coil and capacitor, and a resistor, characterized in that The transistor emitter junction is connected parallel to the diode, and a resistor is connected between the base of the collector.
