The output terminals of a transistor module are open-collector output terminals. If Y0.0/Y0.1 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.
④
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.
