Feedback
The SD-34 and the WD-34 are RailCom compatible, i.e. the decoders
are able to pass the RailCom messages via the rails to special RailCom
detectors. This allows e.g. to feedback the correct performance of
setting and switching commands or the actual setting of points.
Power supply
The decoder can either be supplied by the central unit or a booster. In
order to release the digital electric circuit it is also possible to supply the
decoder by a transformer of it´s own.
