The SSR definitely works with anything else. Will the ones I ordered from China be better suited for the application? Should I just wait and test those?Edit: The SSR has a little red LED on it so I know when it turns off and on, and I have used it for other applications in the past and it has worked perfectly. It must be the inductive load like you said.
The relay modules you purchased use electro-mechanical relays, not a SSR. So your relays use simple mechanical switch contacts to turn on and off the external circuit, just like a standard wall light switch might. SSRs use internal semiconductor parts, a back to back SCR type devices called a triac to do the switching.
