BD-20 Block Detector - Welcome to the NCE Information Station

How does a bd-20 block detector work?
The 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 naturally trigger the detector because they draw current through their DCC decoder.

Does a bd-20 block detector need a power booster?
Unlike other detection units the BD-20 requires no direct electrical connection to the track. This block detector can be used with any sized DCC power booster of up to 12 Amps capacity.

How does a BD20 work?
In a typical application you connect the BD20 to a logic input board using 5 to 12 VDC that reacts to a closed circuit we use it to trigger the inputs of the AIU. Most signal systems work the same way. The BD20 is a detection device and cannot drive a signal directly unless you want to use the external LED connection in some fashion.

What is a BD20 AIU?
An AIU is an input device that detects a 5v line being shorted to ground, such as the output of a BD20. The AIU then puts this information on the NCE Cab Bus. Neither device (BD20 or AIU) are directly related to signaling. They do detection and notification.

How close should a BD20 be to a track?
The BD20 must be as close to the detected section as possible to avoid false detection triggered by long cable runs. For the BD20 to work correctly, ALL feeders for the section being detected must go through the BD20. The best practice is to have one BD20 per feeder and only one feeder per section of track.

How many BD20 feeders do I Need?
For the BD20 to work correctly ALL feeders for the section being detected must go thru the BD20. The best practice is to have one BD20 per feeder, and only one feeder per section of track. That section should be isolated from all other sections by using gaps or insulating rail joiners.
