Current Detected Simply by Passing Wire Through Loop
Douple-Pole Double-Throw Relay on Board
Relay Activated While Current is Detected, Relaxes Without Current
The Trak-DT basic current detector activates its on-board relay when current is detected. When current is removed, the relax relaxes. Current is detected by passing a wire through the sense coil on the board.
Dallee Electronics Basic Detector
All Dallee current detectors require a regulated 12 volt DC power supply. We recommend the 12VPS to power up to five detectors. Please use a regulated source as unregulated power can destroy the electronics on board.
No Current Detected
When no current is detected by the Trak-DT, the right and middle contacts are connected and the left most connector is connected to nothing.
When current is detected, the right and middle contacts disconnect and the left most connector connects to the middle terminal.
Decide on a section of track which will trigger the detector. Isolate one rail (either rail on two rail, center for three rail) for the length of the section of track by adding a small gap in the rail.
Route a new power lead for that section of track, passing it through the sense coil on the Trak-DT board.
Connect the power leads to the Trak-DT. At this point the detector is ready to use. For more detailed wiring guides, please reference the Dallee Wiring Guides.
