    • The present invention relates to a driving circuit for relay, which uses N relays with their coils coupled to each other. One of the relays is coupled to a driving power supply. A switching control circuit is coupled to a second relay and a reference voltage for controlling on/off of the plurality of relays. A driving control circuit is coupled to the plurality of relays for controlling excitation of the plurality of relays. After the coils of the relays are excited by the driving control circuit, the voltage of a single coil is dropped to one Nth of the driving voltage. Thereby, the power consumption of the coils of the relays can be reduced, and hence enhancing the lifetime and reliability of the relays.
    • 本发明涉及一种用于继电器的驱动电路,其使用N个继电器,它们的线圈彼此耦合。 其中一个继电器耦合到驱动电源。 开关控制电路耦合到第二继电器和用于控制多个继电器的开/关的参考电压。 驱动控制电路耦合到多个继电器,用于控制多个继电器的激励。 在继电器的线圈被驱动控制电路激励之后,单个线圈的电压下降到驱动电压的十分之一。 因此,可以减少继电器的线圈的功耗,从而提高继电器的寿命和可靠性。
