Output Circuit: Sink type

24 Vdc External power supply
Sink type
Dummy resistor^*1

*1 (Example) If the output current is 24 Vdc 50 mA, the output delay time (OFF to ON) is 1.5 μs. If more responsiveness is required or the load is light, install an external dummy resistor to increase the amount of current.

NOTE: The output terminals are not electrically protected. A short circuit or poor connection of the output wiring may cause burnout of external devices and this product. If there is a risk of the current exceeding the output rating, connect an appropriate fuse to each output terminal.
