I want to make a dimmer cum fan regulator circuit. For driving AC load (incandescent bulb and FAN) TRIAC gate firing signal generation will be through PIC microcontroller and it is almost complete. Now I need to design the load driver part. Generally TRIAC is used to drive the load. I also want to use it. For isolation I saw uses of MOC30xx series optocouplers.
MOC3031 is "Zero Crossing Triac Driver Output Optocoupler" and
MOC3021 is "Random Phase Triac Driver Output Optocoupler"
What is the difference between these two? There are some circuits given in the application note part of the respective datasheet. So, I can use one of them. But I want to be clear about these things.
