Hi,
I am wondering if anyone knows of a optoisolator or something that I can hook the input side directly to 120V AC and get a sinking logic signal out the other side?
I am having a tough time finding one of these on Digi-Key. I guess I don't quite know what I am supposed to look for.
I have worked with optos plenty on low DC voltage applications; I just am not sure how to detect whether the AC power is on or not.
Thanks
