Review on Electronics Salon SPST NO Module Control Voltage by James Roper

I bought this relay because it activates at 24VAC and I use it with my central air conditioner to power an optional 6" duct fan. in the basement, but the power received was lower than expected, so the automation of an additional duct fan solved the low flow problem. Source to a duct fan. This relay works as expected with no noise. I recommend this solid state relay for the way I use it as it's the only one I've found that works with either AC or DC energizing voltage current.
