PURPOSE: A power line communication duplexing relay system is provided to perform a relay operation by detecting faults in a relay terminal. CONSTITUTION: A relay terminal(22) receives data from a collector. The relay terminal amplifies a voltage level of the data. The relay terminal transmits the amplified voltage to a target terminal through a power line. When there are errors in the relay terminal, a duplexing terminal(21) receives data from the collector. The duplexing terminal amplifies the power level of the received data. The duplexing terminal transmits the amplified voltage to the target terminal through the power line.
