摘要： A current input transducer (13) isolates, by a transformer (14), input current received at a terminal block (11) and converts the input current to a predetermined analog signal, and the analog signal obtained by the transformer (14) is converted to a digital signal by an A/D conversion circuit (18). The terminal block (11) of the current input transducer and one end of the primary-side winding of the transformer (14) are connected with each other by first and second metal plates having a fixed shape. The first metal plate having the fixed shape has one end attached to the terminal block (11) and the other end attached to the one end of the primary-side winding of the transformer (14). The second metal plate having the fixed shape has one end attached to the terminal block (11) and the other end attached to the other end of the primary-side winding of the transformer (14), thereby connecting the terminal block (11) to the other end of the primary-side winding of the transformer (14).

摘要： There are included an input circuit (12) that determines whether an external input voltage is greater than a predetermined threshold voltage, thereby detecting the status of an external device; and an calculating unit (13) that acquires an detection signal, which is obtained by the detection of the input circuit (12), and performs a protective relay calculation. The input circuit (12) includes: a switching means (14) that, when the external input voltage is equal to or greater than the threshold voltage, is rendered conductive by a partial voltage obtained by voltage dividing resistors that divide the external input voltage; and a photocoupler (16) that is rendered operative by a constant current of a constant current output circuit, which supplies the constant current when the switching means (14) is rendered conductive, and that outputs an operation signal to the calculating unit (13).
