Hi,
First you need a zero cross input signal.
Phase angle is just a delay time referred to the zero cross signal.
How to to connect MOC: There is a datasheet, application notes and a lot of reference designes around.

simply this circuit will help you. You will take zero cross detection point and fire the optocoupler depends on duty cycle.thank you for your reply....can u please provide me a link for refernce design??
