As some of you may know, I’m into model trains. These days, most layouts are controlled by what are called Digital Command Control (DCC) systems. One of my “big dream” projects is to build such a system on a NETMF platform. The specs are all standardized by a governing organization called NMRA (national model railroad association). I’m currently in an extended “information gathering” phase of the project, and will be gleaning what information I can from the experts here.
My first question is to @ godefroi specifically. Would your opto-isolated 16 segment “relay” work with +/- 12V bipolar direct current? Take a look at http://www.dccwiki.com/DCC_Power for details of the power modern train layouts use. Almost all of the boards I’ve seen use opto-isolators for controlling various things in a layout, but the stuff is way overpriced IMHO.
BTW - I have searched high and low on the internet for NETMF controls like this and come up empty. There are one or two hobbyists who have had the same idea, but nothing has come of it so far.
