What is the symbol for a solid state relay? I've been using mechanical relay representations in my documentation and just writting next to it "solid state."
I don't like doing this, because it implies that the relay is an inductive load, which it isn't...
My thought is that it should look like or similar to an opto-isolator, with a current path through an LED that's output effects the base of an NPN transistor. Most of the relays we used are isolated anyway, so they probably work this way.
What are your thoughts?
Thanks!
