On a model railroad using DCC, this unit automatically connects the correct DCC phase to the frog of a turnout as a locomotive passes through. Two independent channels are provided and no setup or adjustments are required. The unit can be reconfigured, by changing three on-board jumper links, to act as an auto-reverser, controlling the DCC connections to a reversing loop or wye.
