These adaptor boards greatly simplify set-up and wiring of ABC braking sections. They are simply plugged into the terminals of a SwitchPilot Extension. Every adaptor board can generate the signals for two braking sectors and are wired as shown in the picture.

ABC braking works reliably with all ESU decoders (and others) and facilitates not just a prototypical slow down ahead of a red signal but also allows for triggering functions while waiting for the signal aspect to change. Any sound effects are also maintained.
