AH Motion Controller – Operation Manual Transistor Output Circuit _2 2-16 AHxxEMC-5A Load Trigger Y0.8 Direct-current power supply E mergency stop Fuse 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. AHxxEMC-5A 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. AHxxEMC-5A Y0.9 can not be connected to a power supply directly. It must be connected to a load. AHxxEMC-5A
