An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. I totally agree ,plus MOSFET have a lot much faster switching on/off,and relay have a much shorter life because of it's mechanical contact ,but MOSFET have a forward voltage drop that wastes power ,and they heat up , they have a leakage current that can affect the circuit ,plus it's not completely isolated from it's drain gate and source , I would recommande using TRIAC or THYRISTOR .
