1. a relay control device, it is characterised in that, comprising:

  • master control board and Control plate;

    Described master control board comprises;

    master control chip and fiber optic transmitter;

    The universal input and output port of described master control chip is connected to one end of point compressive resistance, the other end of described point of compressive resistance is connected to the input terminus of the first phase inverter and lower pull-up resistor respectively, the output terminal of described first phase inverter is connected to the control port of described fiber optic transmitter, the other end ground connection of described lower pull-up resistor;

    Described first phase inverter is used for when the relay control signal that master control chip sends is weak pull-up signal, is lower level by the weak pull-up Signal analysis after dividing potential drop, and drives described fiber optic transmitter;

    Described Control plate comprises;

    fiber optic receiver, and described fiber optic receiver is connected with Control port by the 2nd phase inverter, switch circuit successively;

    Described fiber optic receiver is connected with described fiber optic transmitter by optical fiber cable.
