The TSU-PNP incorporates mounting provisions for many of the major diesel model manufacturers, such as Atlas, InterMountain and Bowser, into one board. This 6-function decoder measures 73.7mm x 16.8mm x 4.8mm and is expected to be a top-seller! This board is equipped with a 2-pin connector for the Current Keeper (P.N. 810140) and consolidates most of the original Tsunami Plug and Play-style boards (TSU-AT1000, TSU-BW1000, TSU-GN1000 and TSU-IM1000) into a single design! The 4 part numbers consolidate over 30 part numbers!
