Matt,
Based solely on my own experience, I'm not a huge fan of SSRs for TC
use, for the following reasons:
Our loads are usually highly inductive, and many ordinary SSRs don't
like inductive loads.
The inputs of SSRs are very sensitive, and may be falsely triggered by
the high RF levels inherent in TC work, with undesirable results.
Most importantly, many SSRs have low levels of leakage current, even
when "Off", perhaps just a handful of milliamps. This is no problem if
the load is a light bulb or a motor. However, if you pass this small
current through a step up transformer, you can end up with a really
unpleasant surprise from a "deenergized" system.
For my systems, I use only good old fashioned electromechanical relays.
YMMV.

Has anyone had experience with using solid state relays in medium-size TC Control panels, such as:
