A remote controller using a radio paging network comprises an RF receiving circuit of two-stage frequency converting of a radio pager and a decoding circuit consisting of a single-chip microprocessor and a supporting chip of the microprocessor, wherein signals output from the microprocessor are processed and then supplied to a solid state relay which is provided with one or more ports for outputting the signals. By being provided with different interfaces for different power requirements, it is possible for the controller to control loads different in nature from AC/DC, high/low voltage etc., which will greatly improve the efficiency of a base station in an existing radio paging network without changing operating state of the same and saves investment and radio frequency resources. This invention is applicable to a variety of control conditions.
