I need to construct a circuit that will drive a resistive load (< 8 amps) with a triac operating at 120VAC 60 HZ. I am planning to use a MOC3031M to drive the triac along with a PIC. I have never used a triac in a circuit nor a zero crossing detector. My question is; What is the control scheme, in other words will the pic turn on the triac at the beginning of the zero crossing and then turn it off during some point in the cycle to limit total power? What about RFI issues with this setup?
Thank you,
