(The meanings of the symbols are given below.) 1. The ON voltage of the PLC and the residual voltage of the Proximity Sensor must satisfy the following. VON VCC - VR 2. The OFF current of the PLC and the leakage current of the Proximity Sensor must satisfy the following. IOFF Ileak (If the OFF current is not listed in the specifications, take it to be 1.3 mA.) 3. The ON current of the PLC and the control output of the Proximity Sensor must satisfy the following.
