Hi
Am designing Microcontroller Based Autmatic Transfer Switch for a gen set. I want to use solid state relays (MOC3021) for the control of the engine starter relay. The relay should be powered to start the engine starter when utility power is lost. I want to use about 4 of the relays. How do I connect them to the MCU. Any help (including circuits) will be much appreciated! Kindly find attached my design (the MCU and the AC Voltage sensors)
