I’m new to arduino but have been soldering electronic projects for many years. I was wondering if anyone has recommendations for controlling 110 volt power without resorting to cutting wires, bare soldering relays etc?
I can see there are a few products on the market like the Powerswitch Tail (currently sold out), does anyone have any experience with these? ControllerX looks like a new option (http://www.reversepr.com.au/2017/06/24/ … rt-switch/), any thoughts on that design?
Is there a fully FCC compliant product available? What safety features are people building into their high voltage relay circuits for piece of mind?
There are really no major safety issues connecting a solid state relay (SSR) to an Arduino, as long as you select one with adequate ratings and a “3 to 32” V input, which means the optoisolator LED has a series resistor. Just connect the relay + input to an output pin, and connect the grounds. 1500 volt isolation!
With a proper enclosure you are good to go. I’ve been using them on 220 VAC well pumps and hot tubs for years with no problems.
