SSR dead for the second time

[tofuSCHNITZEL]

Hi,
I have an OG Rev 2.0 and I just had to swap the SSR for the second time in around a year because it was completely fried and did not switch anymore...
maybe this is caused by the particular garagemotor I have but I was just wondering if you have some experience with dying solid state relays on the opengarage board...?

cheers

This is likely due to your garage door system is presenting a high voltage to OpenGarage. The SSR can tolerate up to 60V. I've seen very occasionally some garage door systems that present 110V, which will definitely fry the SSR. Have you measured the voltage on the two wires of your garage door system? Almost all modern systems use 12VDC, which is well below the limit. If this continues to be a problem, you may want to use an electromechanical relay which can tolerate up to 220V.

I admit I have not yet measured the "switching" wires because I assumed that they come pot-free from the garage motor pcb... but probably not ;) I have wired a "real" relay to the opengarage pcb and I don't expect any issues anymore ;) thanks!
