1. a power distribution cabinet signal acquisition module, this acquisition module is provided with analog output terminal, digital output terminal, and multiple straight-through current transformer, multiple digital-quantity input terminal;

  • Described analog output terminal, digital output terminal are plug-in type connection terminal, and analog output terminal, digital output terminal respectively have a common port pin and multiple signal end pin;

    The quantity of described straight-through current transformer is consistent with the signal end pin quantity of analog output terminal, and one_to_one corresponding;

    Described straight-through current transformer has two current output terminal pin, and one of them current output terminal pin is the first output terminal pin, and another current output terminal pin is the second output terminal pin;

    First output terminal pin of each straight-through current transformer receives the common port pin of analog output terminal respectively, and the second output terminal pin of each straight-through current transformer receives signal end pin corresponding on analog output terminal respectively;

    The quantity of described digital-quantity input terminal is consistent with the signal end pin quantity of digital output terminal, and one_to_one corresponding;

    Described digital-quantity input terminal has two digital quantity input end pin, and one of them digital quantity input end pin is first end pin, and another digital quantity input end pin is the second end pin;

    The first end pin of each digital-quantity input terminal receives the common port pin of digital output terminal respectively, and the second end pin of each digital-quantity input terminal receives signal end pin corresponding on digital output terminal respectively;

    It is characterized in that;

    the length of described analog quantity connection terminal and the length of digital quantity connection terminal different, and the end pin spacing of the end pin spacing of analog quantity connection terminal and digital quantity connection terminal is different;

    The end pin spacing of analog quantity connection terminal refers to, the spacing on analog quantity connection terminal between adjacent signals end pin;

    The end pin spacing of digital quantity connection terminal refers to, the spacing on digital quantity connection terminal between adjacent signals end pin.
