    How are you using 24VDC Ports?

    How’s everyone using these? I thought about using these to turn my canopy fans on/off. However, after ordering the bare cables, I realized my fans are AC and that’s not gonna work.

    So, I’ve got two of the bare cables and I’m just curious how I could possibly use them? What are some common uses?

    The only thing I'm using them for is audible alarms.

    I use them to turn on/off small muffin fans used to cool the water on both my salt and fresh display tanks. The muffin fans are 24 volt DC fans that I run at 12 volts to reduce the noise. I use an adjustable buck converter to step down the 24 volts for each. It's small, has a backlit display that lights up whenever power is applied so that I know when the tank is getting too warm.

    I also use mine for a piezo buzzer alarm siren. And I have one controlling a backup solenoid in my topoff water line.
