It will certainly replace the 153C contactor, it has both a normally-open and normally-closed set of contacts. In point of fact, there is actually another set of contact on the board to a second header so you get even more functionality. Also, there is a jumper option to allow you to apply either power or ground to the center common contact, or you can isolate it and connect your own. It more than replaces the 153C.
John:
Thanks. All understood. The way people were talking about using it to run gatemen, semaphores, and gates, I got confused.
Using this for block control (like a 153C or an insulated rail connected to a chatter-y old fashioned relay) is what I'm after. I'll take 5 whenever you finalize the design and production. Like RTR12, there's no rush on my part. Please take the time to get it right at a pace that's enjoyable for you.
Thanks for doing this.
