Hi I'm looking for a way to switch an external 24v with the 5v Arduino output I currently have sort of working with a transistor but id need multiple and I'm out of board space anyone know of a relay arrangement/module I could use that will work reliably and doesn't take up much space thanks.

High-side or low-side switching?
