Quick demonstration of Circuitron's AR-2 Auto reverse circuit. HO scale cable car on a DC circuit. Time at stops is adjustable from 0 to over a minute. Kit comes with circuit board and two light sensors. 2 power sources are required, adjustable DC and a constant DC or AC. Note you can not use AC if bundling with DT-4 for delayed stops without reverse.
Is this unit running only off of power from the transformer? Does it come with instructions?
