Can a 240V SSR be used to switch voltages below that? eg. 110V, 24V etc?

Yes. Keep in mind that any SCR drops about 1.2 to 2 volts regardless
of its voltage rating. This is a lot more significant when switching
24 volts than when switching 240 volts.

Hi, Peter. The data sheet for the SSR specifies maximum and minimum voltages,
as well as maximum and minimum current. I believe most 240 VAC SSRs are
specified to switch 24VAC.

Good luck
