Jun 21, 2019 at 19:09 comment added Duncan C i added a note to point out that these are not really solid state relays. (And the relay I link to is a 3V relay. Look at the picture.)

Jun 21, 2019 at 19:05 comment added Duncan C Vendors use the term solid state relay when they really shouldn't. It's a relay module with circuitry that enables you to switch it with low current logic level signals. I was being lazy by using that term, and should not have.

Jun 21, 2019 at 16:02 comment added Juraj This answer is so wrong. This is not a SSR. And there is 5VDC on it. And the relay on link is not SSR either.
