ESU 51970 Input Output Expansion Board 21MTC

For LokSound, LokPilot V4.0 21MTC. This expansion board is for  LokSound & LokPilot V4.0 21MTC decoders. With this expansion board you can easily expand your LokPilot V4.0 or LokSound V4.0 decoder (with 21MTC interface!). All you need to do is to plug the decoder onto the expansion board and benefit from using 4 additional function outputs (AUX5 through AUX8) for lighting effects, coupler etc. In addition, you are able to connect 2 RC-servos! The 5V voltage needed (for this) will be also provided. The expansion board has control electronics for synchronised smoke units. You just need to install an ESU smoke unit into your locomotive and the board can generate synchronised steam chuffs or Diesel smoke.

With a LokPilot/LokSound V4.0 decoder, all functions can be controlled directly and are fully integrated into function mapping. The board measures 15.5mmx 30mmx 5.5mm (0.61 x 1.18 x 0.22 inch) and is the exact size of a LokSound V4.0 decoder.

The module can be directly plugged into a 21MTC interface of a loco (if enough height available) or freely wired via its cable connections.
