Mark if you are working with DCS and need relay info, call or e-mail me. We are doing relays with AIUs for both turnouts and track power now and can probably tell you what you need and send you a couple of wired relays to start with.
Thanks to Stan a few years ago, we have almost “mastered” the AIU/relay job.
We just reordered a month ago and got a bunch.
I think that you have our information.
