A digital device for detecting defects of lines is provided to simplify the construction of a system by directly receiving a digital signal to construct the system. A digital device for detecting defects of lines includes a case, a PCB(Printed Circuit Board)(500), a control unit, a voltage regulator(560), a lamp output unit, and a relay output unit. The case forms an appearance. The PCB is included in the case. The control unit is mounted on the PCB, converts an analog signal into a digital signal, and detects whether the lines are abnormal by selecting and operating a plurality of line signals. The voltage regulator regulates an applied voltage to be a voltage available in the control unit. The lamp output unit is mounted on the PCB and displays defects detected by the control unit. The relay output unit is mounted on the PCB and outputs defects detected by the control unit to an additional control unit. |
