HO Scale DCC Block Detector Occupancy Detector Circuit 5V 12V

Description

Up for sale are these custom designed Block Detectors / Occupancy Detectors made for DCC Systems. Their purpose is to detect whether or not a section or block of track is occupied. They can be used for signaling purposes, or any other reason you may want to know the location of a train on the layout. Can be powered by 5 or 12 V, and the optional relay can be used to open/close upon detection of occupancy. These are completely built and operational, the only parts that are missing are the optional delay capacitor, and the optional relay. Includes an Green LED that indicates Power ON, and a red LED for indicating occupancy. You will also see an image of locations for outputs, both active high and active low.
This board was not designed by me, I just had it made and built it. To see the full article and documentation of this design, go to Model Railroad Hobbist site and search "Build a simple block occupancy detector".
I bought these and built them myself intending to use them on my own layout, but went in a different direction.
Thanks for looking! feel free to make an offer, especially if purchasing more than 1 qty.
