Automation HAT - Detecting 24v Input

I’m somewhat new to electronics, I’m trying to wrap my head around something. The Automation HAT has inputs that say they are 0-24v tolerant.

Does this mean I can power one end of a 24v switch with an external DC power supply and plug the other end directly into one of these 24v inputs to detect when the switch is closed?

Thank you for your time.

Yes, it doesn’t have to be 24V though. It’s “up to” 24V. You could send 5V or 3V in.
