The 6090 decoder was the
first for Märklin H0 locomotives that used electro-magnetic feedback to
create a speed regulation that keeps the loco at constant speed both up
and downhill, and also independent (to a certain limit, of course) of
the load of the wagons. This is also the first H0 decoder from Märklin
that allows acceleration/deceleration and maximum speed to be set. The 6090 is a complete set with a special DC motor to retrofit locos with the DCM motor. The set contains this
The decoder has the chip version 701.13 aboard, and this means it doesn't recognize the absolute direction component in the "new" Märklin data format. But it runs well anyway.
Here we use the controllable function to switch TELEX couplers, or a smoke unit. To still have lights, diodes (1N4148) and Zener-diodes (BZX83C2V7) are inserted. The lights are connected to the red cable (track power) and are constantly on. |
