Arduino solid state relay ac fan control

Projects General Guidance

Hi. I want to control four AC fans with arduino. All I want to do is just turn them on or off at specific intervals.

Will this schematic work?

Arduino ssr fan control schematic

Following are the components.

Arduino UNO.

4 ac fans that run on 220v and around 120w. So current is roughly 0.55 amps. (Correct if wrong. Going by wattage = amperage x voltage)

a, b, c and d are Solid State Relays (DC to AC) with AC 24 to 380v with 10amps and DC 3 to 32v.

That will work just fine, if you get rid of the + and ground on the AC side. The AC side of the SSR operates just like a manual switch for your AC control of the fans.
