What this does for the everyday railroader WHO USES ROSS SWITCHES is allow better control over powering (and not powering) certain isolated rails that can cause either a loss of power or a momentary short when wheels run over those isolated rails.
This replaces and improves on the functions of the DZ-1008 relay; that although nice was a bit of an overgrown after thought for the DZ-2500C switch machines. The DZ-1008 worked well when plugged into the DZ-1000 switch machine that it was intended to support; but not so much when used in conjunction with the DZ-2500C switch machines.
Also, most of the specialty turnout wiring diagrams displayed on both ROSS's and DZ's sites are for the DZ-1000s. It takes a bit of electrical engineering knowhow ( for me trial and error) to interchange those diagrams for the DZ-2500Cs. This relay looks like it makes that interchange a lot easier.
