Exo Active Member Oct 17, 2004 #1 I'm making something similar to the circuit in this app note https://www.electro-tech-online.com/custompdfs/2004/10/40171a-2.pdf (scematic on page 10 - the pic's output is high to fire the triac and Hi-Z for no fire) I need to know in wich quadrants the triac operates when it is setup this way. I figure it's in quadrants 1 and 4, can someone verify this?
