Hi All,
Attached is the result of your help and my efforts. I was able to use Eric's information to learn quite a bit about LTSpice. But I have yet been able to install non-LT components into the program! Nevertheless, I have obtained some decent results.
The attachment will show that I have decided to go off board with a zerocross SSR. It is more expensive, but easier for me to model. You will see that the circuit simulates nicely with a few ms of hysteresys. The hysteresys is very easy to see when simulating different positive feedback resistors.
I added an additional cap to shunt spikes the hysteresys may not avoid. I am not sure the cap is necessary or of appropriate value. Opinions?
While the circuit simulates well, the real world may well be different. So, if you see component values that might be modifed for better stability and longevity, please let me know.
Thanks for all the help you all have provided and special thanks to Eric who helped me get into working with LTSpice.
