Solid State Relay (SSR) using MOC3020




The circuit  uses the MOC3020 optocoupler that drives the triac to switch 220V of AC volt to a load. We have this project after one of our incubator heater failed due to a faulty mechanical relay. The triac on this circuit can be directly mounted on a suitable heatsink without a need for an insulator. The original circuit was taken from the MOC3020 Motorola datasheet.    ---73 de hevir
