The 21MTC breakout board provides a handy way to access all outputs of 21MTC decoders for hardwire applications. Very similar to the ESU 51967 21MTC adaptor board.
21MTC decoders typically feature up to 8 amplified outputs and at least 2 logic level un-amplified outputs, more than other decoder types. Use of the breakout board will allow access to all of these functions. This may be helpful for locomotives not equipped with a 21MTC socket.
Note: this product is not designed for locomotives already fitted with a 21MTC socket.
