For the digital control of Roco H0 Turntable 42615!

Suitable for the digital formats Märklin-Motorola and DCC.


The TurnTable-Decoder TT-DEC-R is suitable for the digital control of the Roco H0 Turntable 42615.

The Roco H0 turntable 42615 can be equipped with 4 up to 40 track connections.
Non-aligned opposite track connection can be assembled at a min. of 4,5 degree offset.

The command-set of the TT-DEC-R is compatible to the Märklin Turntable electronic 7686. Therefore is a very simple control via any Digital Command Station and Model railway software possible, which supports the Märklin turntable electronic 7686 with a turntable graphic.

The digital format (Märklin-Motorola or DCC) and the location of the track connections are easily programmable via any digital command station which is able to switch turnouts or via a model railway software which supports the Märklin turntable electronic 7686. Any track connection of the turntable can be programmed as track 1 (reference track).

The TT-DEC-R permits the step by step rotation to the right- or left side, the direct connection of pre-selected tracks and turning the movement direction of the turntable by 180 degree.

The rotation speed of the turntable can be individually adjusted via a potentiometer. The motor of the turntable receives a stabilized direct voltage for a steady turning movement of the bridge track.

The plug of the 8-poles flat ribbon cable of the Roco H0 turntable 42615 shall be plugged directly onto the pin-plug bar of the TT-DEC-R.

The bridge track receives the correct polarity from an integrated switch-over relay. Therefore is no additional reverse loop module for the bridge track required.

If the turntable will be in the lined-up track position this can be reported to the model railway software via the feedback output of the Turntable-Decoder TT-DEC-R.

There are no mechanichal changes needed to the Roco HO Turntable 42615. There are only two small electrical adaption necessary. After completion of the electrical adaption is it not anymore possible to control the Roco Turntable 42615 by use of the Roco manual control unit.
