I'm working on a project that controls 12V 5A heater with pic Microcontroller, I need to control it without relay. So I designed a circuit using optocoupler (PC817) and two power sources (Vcc 5V for PIC, Vpp 12V for heater) for isolation, I need to know if this circuit will work good with this heater or not and if there is another idea for isolation?
Thanks in advance,
