、１方のフオトカプラには入力ポイントが正電位
で、他方のフオトカプラには入力ポイントが負電
位でそれぞれ電流が流れる様にし、両フオトカプ
ラの出力信号により正負判別する様にしたことを
特徴とする正負判別回路。 Connect two photocouplers to the input point, and make current flow through one photocoupler with the input point at a positive potential and the other photocoupler with the input point at a negative potential, and determine whether it is positive or negative based on the output signals of both photocouplers. A positive/negative discrimination circuit characterized by being configured to do so.
