DCC Concepts DCD-ZN8H-5 ZEN NANO 8 Pin Wired 2 Fn Decoder w/Stay Alive (5 Pack)
One of the smallest decoders produced by DCC Concepts. This decoder is only 15mm long so it can be hidden inside any locomotive either steam, diesel or electric.
This pack includes a stay alive unit which are designed to aid your locomotives running characteristics during slow running. This unit basically keeps the decoder "alive" for a few milliseconds if dirt or dead spots are located on the track.
