A relay or a solenoid valve is used as a DC load. A diode is connected in parallel to absorb the surge
voltage which occurs when the load is OFF.
⑥
An electromagnetic contactor is used as an AC load. A resistor and a capacitor are connected in
parallel to absorb the surge voltage which occurs when the load is OFF.
⑦
A bulb (incandescent lamp) is used as a DC load. A thermistor is connected in series to absorb the
surge current which occurs when the load is ON.
A bulb (neon lamp) is used as an AC load. A thermistor is connected in series to absorb the surge
current which occurs when the load is ON.

Mutually exclusive output: For example, Y0.4 controls the clockwise rotation of the motor, and Y0.5
controls the counterclockwise rotation of the motor. The interlock circuit which is formed, and the
program in the PLC ensure that there are protective measures if an abnormal condition occurs.
