The 21MTC 2 adapter board is also suitable for digitizing a locomotive without an interface. It is very useful if you do not want to wire the decoder freely or if you want to use more than 4 outputs on your LokPilot or LokSound decoder. This adapter board simulates the typical size and shape of Märklin® 6090x decoders and can be installed in any suitable position.
Decoders with 21MTC connectors (preferably ESU LokPilot or LokSound) connect easily to the adapter board.
On the output side, the adapter provides pre-soldered cables (approximately 20 cm long) for all necessary contacts. This makes wiring your locomotive very simple. Amplifiers (approximately 250 mA each) are available for the AUX3 and AUX4 functions (the decoder's logic outputs), so ESU decoders have up to 6 physical function outputs.
