Adapter board for "21MTC" decoders; the decoder is plugged into the pin connectors of the adapter board. Via large solder pads the wiring inside the loco is very comfortable. The adapter board ADAMTC is equipped with a rectifier which relieves the decoder's rectifier and so produces less lost heat and performs better.
The adapter board ADAMTC can be used with following "21MTC" decoders ( C-types): MX631C, MX634C, MX638C, MX644C, etc. and their successors.
DO NOT USE MS440C, MX636C and D-Types like MX631D, MX634D, MX636D, MX638D and MX644D, whereas some of them can be turned to the corresponding C-type by pseudo-programming: CV #8 = 3.
For the connected decoder, the values of the supported energy storage modules only change to 16V/max 6800µF, if the energy storage module is connected to the corresponding solder pads/screw terminals of the ADAMTC/ADAMKL boards.
This combination works well for O-scale as an alternative to large-scale decoders (although with fewer function outputs, low voltage outputs, and other large-scale specialties).
