NCE Corporation BS-20 DCC Block Detector. This block detector is used to indicate the presence of a locomotive or any rolling stock in a section of track by sensing the electrical current drawn by that rolling stock. The Logic Output of the detector is an "open collector". This type of output is compatible with most signal system logic boards on the market today. Package includes one BD-20 block detector.


NOTE: Unpowered rolling stock will not trigger the detector unless equipped with some means of drawing current from the rails such as lights or resistor wheel sets.
