WebKB497 BD4 - Connecting to an SE8C Connecting BD4 to an SE8C?The BD4 is a block occupancy detection device designed as an add-on device that can take advantage of the LocoNet hosting capability of the SE8c signal decoder. It is connected this way: The installation of a BD4 is relatively simple. WebApr 9, 2008 · I would use a very simple block occupancy detector on both "legs" of the crossing. If there is a train present it trips a relay cutting power to the other leg. Depending on the exact design there could be problems with either flickering (optical dectection) or train length (current detection). Neither are really hard to overcome.

WebThe BD-20 block detector module is normally used to indicate the presence of a locomotive, caboose or other rolling stock in a track section by sensing electrical current drawn by that rolling stock. Locomotives will … WebOct 5, 2024 · For block detection, we want to know if there is any rolling stock in a given section of track. The prototype does it by applying a voltage across the rails-- any axle on the track will bridge the rails and draw a current. That current throws relays and things happen. Since you are a dead rail guy, you could easily do something similar.

Here are the steps to prepare your track for detection: 1. In order to get detection working, you first need to select a section of track you wish to detect if a train is on that track. 2. Isolate this section of track by gapping one of the rails at the start and the end of the block. 3.
