Transistor Output Circuit
The AH500 series transistor outputs are equipped with the diodes which provide the
counter-electromotive force protection. They can be used if they do not switch between ON and
OFF states frequently and there are low-power inductive loads. If they switch between ON and OFF
states frequently and there are high-power inductive loads, they must be connected to noise
suppression circuits to reduce the noise and prevent the overvoltage or the overheating from
damaging the transistor output circuit.
The NPN/PNP transistor output circuit
①
Direct-current power supply
②
Emergency stop
③
Fuse
④
The transistor outputs are open collectors. If Y0.0/Y0.1 is a pulse train 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.
