I/O Expansion Board 21MTC

The LokSound by ESU I/O Expansion Board 21MTC is for expanding a LokPilot V4.0 or LokSound V4.0 decoder with a 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 servo control is provided by the board. The highlight of the expansion board is surly the control electronics for synchronized smoke units. You just need to install an ESU smoke unit (from Class 215) into your locomotive that allows to generate synchronised steam chuffs or diesel smoke.
 
With the help of the LokPilot or LokSound V4.0 decoder all functions can be controlled in a direct way and are fully integrated into function mapping. The board measures 0.61 x 1.18 x 0.22" 15.5 x 30 x 5.5mm 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 is available) or freely wired via its cable connections. The I/O Expansion Board 21MTC is part of the broad assortment of ESU DCC accessories.
