Take digital control of your narrow-gauge fleet with the Busch 12390 digital decoder, designed for Busch Feldbahn and mine railways driven by a 3 V micro-motor. With item 12390, these locomotives can be operated from a digital command station without any modification to the loco itself. The decoder provides five traction outputs, one permanent output plus four that can be switched via the function keys of your command station, allowing the driving current to be routed to four separate track sections.

The Busch 12390 decoder works with DCC command stations from all manufacturers as well as all Märklin systems. In DCC operation it supports 14, 28, or 128 speed steps and long addresses; in Motorola mode it offers an address range of 1 to 255 (only 80 addresses with the Märklin 6020/6021). Starting and maximum speed as well as acceleration and braking delay are all programmable. Item 12390 is also suitable for conventional DC operation, so loco speed can be controlled with a normal transformer up to 16 V DC.
