Review on 🔌 Opto-Isolated Support Module for HiLetgo Channel by Wesley Carreras

I used this on an Ender 3 V2 3D printer to allow the computer to control the power and LED lighting. Works perfectly! Easy to install and support the performance needs I had. The clicking is audible, but then again it's not solid so that's to be expected, but it's definitely not super loud or anything. Screw terminals are a nice feature! Updated rating. The relay worked but when the coils were de-energized they stuck and were released by tapping lightly with a screwdriver. To return.
