800-5502 BD-2 Block Occupancy Detector- Current Sensing

The BD-2 also incorporates a turn-off delay of approximately ½ second to prevent loss of detection due to dirty wheels, etc. The BD-2 will directly drive either LED-type or incandescent lamp, 2-color block signals and the outputs have a maximum current capacity of 250 ma. The circuit boards are designed for easy daisy-chain wiring of multiple blocks and will snap into a section of our PCMT (Printed Circuit Mounting Track) for simple installation. The BD-2 is constructed on a 2” x 3” printed circuit board and is available in standard 3-amp track power capacity (which is adequate for HO and smaller scales)
