Direct-current power supply
The output terminals of a transistor module are open-collector output terminals. If Y0.8 is a pulse train output
terminal of a transistor module, the output current passing through its output pull-up resistor must be greater
than 0.1 A to ensure that the transistor module operates normally.
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.
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.
Y0.9 can not be connected to a power supply directly. It must be connected to a load.
Mutually exclusive output: For example, Y0.10 controls the clockwise rotation of the motor, and Y0.11 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.
