John_R Posted June 19, 2021 Report Share Posted June 19, 2021 Hey All, I'm playing with one of my home projects where I have a 6" "boxer" fan (120vac 85W) cooling some components. The fan is currently controlled from my PLC with a PNP output turning on a random crossing SS relay (AD-SSR810-DC-48R). I would like to slow down the speed of the fan, and seems it should be just a matter of adding HSO/PWM to the output? But I've not done this before, so before I let the smoke out of things here, I figured I'd ask for opinions... What do you'all think??
