Direct-current power supply Emergency stop Fuse
The transistor outputs are open collectors. If Y0.8 is a pulse output, the output current passing
through the output pull-up resistor must be larger than 0.1 A to ensure that the transistor
operates normally.
Relay/Solenoid valve through which the direct current passes: A diode is connected in parallel
to absorb the surge voltage which occurs when the load is OFF.
Bulb (incandescent lamp) through which the direct current passes: 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 the power supply directly. The output wiring must be connected to
a load.
Mutually exclusive output: 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.
