PURPOSE: A device and method for controlling input signals of plugboard terminal is provided to control input signals by using switches of radio remote controller or any other relevant devices. CONSTITUTION: A device and method for controlling input signals of plugboard terminal includes the following components. A current transformer(CT) reduces the level of signals after receiving power. An A/D converter(12) converts the output signals from a primary resistance(R11), secondary resistance(R12), third resistance(R11, R12, R13) to digital signals. A controller(14) conveys the output signals from the A/D converter(12) to the indicator(15). A remote control(10) outputs infrared signals according to the input orders by a user through a keyboard. A remote-control receiving unit(11) receives the infrared signals from the remote control(10). A key processor(13) inputs key signals according to the input signals by a user. A memory(16) operates the submitted signals from the key processor(13) and the remote-control receiving unit(11) and stores the signals.
