800-5522 BD-2HD Block Occupancy Detector- Current Sensing

The BD-2HD incorporates a turn-off delay of approximately ½ second to prevent loss of detection due to dirty wheels, etc. The BD-2HD 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-2HD is constructed on a 2” x 3” printed circuit board and is available in standard 6-amp track power capacity.  The signal driving capacity of the BD-2HD is increased to 500ma. per output and will work well with large scale equipment.
