Replacement for DZ-1008 Relay for Ross Switch Powered Rails

I don't have the Turbo Train, so I'm not worried.   So far I haven't seen any issues with the speed that the DZ-2500 activates the non-derailing feature.  Obviously, the switch isn't instant with the tiny motor, so I see that as a lot more of a risk than the couple of milliseconds the relay takes to do the actual switching of the fixed rails.

Yeah, my speed of the train is pretty extreme to get a short.  Grandchild found this one.  😁

Good thing I sent the boards for a prototype run to OSHPark, I had the wrong footprint for the relay!  OOPS!  I also noticed a couple of spacing issues, but a kludged one together and it works, so I just need to correct the mechanical issues and I'll get a bunch of PCB's.

I would commit to a bunch of them.

If these are a complete item, I'll buy 10 minimum.

Well, they will be complete when I get the new boards.  I went for another spin of three to make sure everything lines up before I order a big batch.

I'm late to the thread here, but it looks like you have another neat device here that might fill a need for many! Looks good!

I need a stiff Bourbon.  I completed wiring up a Ross #6 crossover and two Ross #8 curved turnouts last weekend, with the DZ-1008, and screwed the track down.  Ordered 4 more DZ-1008s to cover additional turnouts not considered in the earlier order, a week ago.  Obviously, this is a vastly superior solution, not only because of the common rail selection but also because it eliminates the dependency on the grossly undersized DZ-1008 relay contact wires (what's the point of a 10A relay with #24 wires connected to it, despite their short length?).  At this point, I'll have to try out my inventory of rolling stock to see if I'll have any problems, before I pull things up and rewire (or add ugly visible wires soldered to outside of rails).

John,

I went through the topic and did not see the amps yours will handle.

The relay I have is a 5A relay.  I can't imagine one engine drawing power needing 5 amps, and the 10A relay would have been much larger for a DPDT relay.

Mr New here. I could use a little help on explaining some of the abbreviations. Thanks. To GRJ for all the sharing of info

Which abbreviations are you confused about?

I have no idea what Ms.MSS means.
