Circuitron 800-5502 BD-2 Current Sensing Detection Unit Wheel Sets - 28" detailed scene with a drive-inCircuitron 800 5502 BD 2 Current Sensing Detection Unit Detects current drawn by a locomotive or lighted piece of rolling stock. Unpowered equipment can be detected by using metal wheelsets with resistors connected across the insulator. Will directly drive 2 color lamp r LED type block signals. 250 ma. output (500 ma. for BD 2HD). Circuit boards are designed for easy daisy chain wiring of multiple blocks and will snap into a section of Printed Circuit
