Light-Signal Decoder for light signals of the Nederlandse Spoorwegen (NS)

for NS train signals equipped with LED (light emitting diodes) for the data formats Märklin-Motorola and DCC from our Digital-Professional-Series !

The Light-Signal Decoder LS-DEC-NS can perform a realistic control of up to 4 signals of the Nederlandse Spoorwegen (NS).

Features of the LS-DEC-NS

Realistic switching of light-signals via accessory addresses:

  • With the Light-Signal Decoder LS-DEC is it possible to switch light signals via accessory addresses. Ideal for Digital Central Units which are switching turnout tracks and Model Railway Layouts which are controlled by PC and control software. The signal wiring will be simply connected to the signal-module by practical and secure clamps.
  • Up to four 3-aspect signals can be controlled by one Light-Signal Decoder LS-DEC-NS. Is there a indicator sign installed this signal will lighten by slow proceed aspect as well.
  • The signal lamps will be switched realistic from STOP (red) to PROCEED (green) via the aspect SLOW PROCEED (yellow).

  • Signal aspects will not simply be cross faded but as realistic the prior aspect will be firstly dimmed and after a short dark phase the new signal aspect will appear. The light emitting diodes will be dimmed up and down during this process.

above: conventional signal change by simple switching. below: realistic signal change with dim- and dark phase with the Light-Signal Decoder LS-DEC.

  • With integrated series resistor for the light emitting diodes.
  • Suitable for all LED-light signals with common anode or common cathode.
  • The signal current has not necessarily to be supplied by a booster but can be directly feeded into a separate input from a model railroad transformer. This saves expensive digital current.
  • By using a connector plug you can choose if you want to operate the decoder on a Märklin-Motorola system or on a digital system with DCC Standard.
  • Decoder of the Digital-Professional-Series can be used on your digital system without any problems because they are compatible to the Märklin-Motorola-Data format respectively to the DCC standard.
  • The finished module in a case comes with 24 month warranty.
  • Each decoder LS-DEC-NS will be supplied with a detailed operating-instruction.
  • You can purchase the Light-Signal Decoder as tested finished module in a case (-G).
