Heating controller – Triac board

Hi, I successfully designed, etched and build triac board for my central & water heating controller. Board is divided into two parts: Triac & optocoupler part Power supply part   Board features four BTA12 triacs that are driven by MOC3063 optocouplers and have snubber circuit. Optocouplers input will be controlled via MSP430 microcontroller. Power supply […]
