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 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 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 a 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.
2. Wiring differential output terminals
Take AH10PM-5A for instance. The wiring of the differential output terminals on AH10PM-5A is
described below.
