Technical Discussion on BDL168/BD4 - Mark Gurries. Background Circuit Information: BDL168 and BD4 DETECTION METHOD: The Detection method is done by monitoring the voltage drop across two back to back diodes created by the current flowing through them.
However only one polarity (One DCC phase or one diode of the two) is monitored for voltage drop. The detection assumes the current will be the same in both directions and hence the voltage drops will be the same in both directions. Hence only on direction or DCC phase needs to be monitored for voltage drops. BASE SENSITIVITY: The BD168 and BD4 are designed to be sensitive enough to detect a 10K resistance on the rails. BASIC ISOLATION: The BDL168/BD4 itself do not need any isolation from any Booster or autoreversing devices that feed them. Layout Wiring Channel/Tray.
Switches. Wiring Turnouts Welcome to the website that coined the phrase "DCC Friendly!
" This is the most popular section of this web page! If you are a manufacturer, talk to your DCC customers. Consider making DCC friendly turnouts - I tell you how below. Modelers, write your favorite manufacturer. Check out Dale Muir's railroad information page for turnout terminology. To see a schematic of a turnout wired to trackwork, see the trackwork section of this web page, suggestion 5-7. Menu_Train_Miniature. DCC Circuit Breakers - Mark Gurries. DCC Circuit Breaker HistoryThe purpose of Layout circuit breakers is to manage power going to different parts of the layout such that there is not a total loss of power when a short develops someplace on the layout.
It is not unlike the circuit breaker panel on your house. It something shorts out, you do not lose all the lights and power in the house. Circuit breakers, unlike a fuse, do not require any parts to reset them. Hence it is easy to recover from a fault. The circuit breaking element be it a bulb, semiconductor switch or relay is wired in series with the track. The track current runs through a monitor or sensor of some kind so it can sense the current. True On-Off switches have an extremely low resistance measured in Milli-ohms (0.001 ohms) and almost an infinite resistance measured in Giga-ohms (1,000,000,000 ohms). DCC for beginners. DCC for Beginners If you are new to DCC and are wondering what it is all about, this section is for you.

Our layouts and landscapes aren’t just there for viewing. The electronics make things happen. Trains travel, lights come on and off, switches switch, campfires burn, signals change, smoke comes out of the stacks, train whistles blow, with the sounds of chugging in the background, video cameras attached to trains give you a front seat cab view of where the trains are going or a caboose view of where they’ve been, neon signs light up buildings and billboards, street lamps light up city streets, etc., etc. France - Rocrail.
