BOD-1
(Block Occupancy Detector-1) This inexpensive self contained diode drop detector works with both analog DC and DCC layouts. It has dual opto isolator outputs which allow it to drive virtually any signal logic designs, and of course it may be used as an input to our TC-64 and LNCP LocoNet interfaces. The BOD-1 uses 3A Schottky diodes for minimal voltage drop across this unit when compared to other diode drop style detectors. This little (1" x 2")  detector is much too small to fit into the 3TK-2 snap track mounts. Manual
