Multiprotocol-decoder 76 500
Digital Operation on Layouts using either DCC- or Motorola-Format for Locos with DC-Motors.
Description
The 76 500 is a powerful, small-outline, multi-protocol-decoder. It can be used in DCC- or Motorola-
systems as well as in analog DC-mode or AC-operation using the overvoltage pulse for reversal
(Märklin-System).
The decoder employs a chopper frequency of 18,75 KHz and is therefore not only suited for all
standard DC-motors, but also for instrument motors such as Faulhaber, Maxon or Escap, drawing
up to 1 amp continuous current. Surges of short duration are also tolerated.
The speed characteristics are either set by the minimal, intermediate, and maximal speed CVs
or by the individual speed step CVs.
The load compensation parameters can be trimmed to match the individual loco’s properties.
The decoder features two direction-dependent headlight outputs, and two additional ancillary
outputs controlled by F1 und F2.
The function keys F3 und F4 may activate switching mode with an extended slow-speed range,
and acceleration/deceleration. All tasks of output switching and calling up of functions may be
freely assigned to any function key (Function Mapping).
The decoder can be programmed by Intellibox, or any DCC or Märklin/Motorola control unit. All
CVs can be accessed.
By default, the decoder recognizes DC, AC, or digital operation and adjusts itself automatically.
The operation mode can be manually selected, too.
