The printed circuit board 8069 was developed for Märklin locomotives of the Re 460 series and various Ae 6/6 to digitize them in the easiest and cleanest way. The PCB is equipped with a 21MTC interface, all important connections are lead out to large solder pads.

The decoder outputs Aux 3 and Aux 4 are amplified on the circuit board and can therefore be used for the direct connection of consumers.

The PCB is therefore ideal for connecting our light modules 8086 (for the Re 460) or 8085 (for the Ae 6/6) with red and white LEDs.
There are two diodes on the circuit board. These ensure that the white lamp at the bottom right is always lit when the other white lamps are lit (A-light).

If necessary, two more diodes (D1 and D4) can be fitted. This allows the Swiss light change without changing the decoder settings (only useful for locos without red tail lights).

The PCB has a size of 32 x 18mm and fits therefore exactly into the Re 460 and some Ae 6/6 instead of the existing light change PCB and is fixed with the existing screw.

Use a decoder without amplified aux outputs for this article. Aux 3 and Aux 4 are amplified on the PCB and are led out on solder pad. The Aux 3 and Aux 4 connectors provide the full decoder voltage and can be used to connect loads directly.

The two articles 8067 and 8068 are similar to this article, but the Aux 3 and Aux 4 connectors are unamplified.
