I want to use a Raspberry Pi to drive this relay. It is solid state, SP/ST, needs 12V for the coil and can switch up to 16A at 250V AC.
Now, I know that The RPi cannot switch natively anything above 3V and I have already found a circuit doing just that, switching a 12V relay from 5V logic.
My question is this. Is there a better way to do this? I would really like something a bit more "professional" because it will go in the electrical cabinet as part of a permanent installation. Ideally, I think, this should be electrically isolated from the RPi and also have some sort of protection, in the form of a fuse or something like that.
