The Circuitron DT-2 is a fully assembled grade crossing detector for DC model railroad layouts. It uses four Opto-Sensors and bidirectional detection to reproduce realistic crossing activation for short or long trains.
Product Details
-
Material: Fully assembled electronic circuit on a 3 x 3 inch printed circuit board.
-
Scale: Not specified; designed for model railroad layouts rather than a single scale.
-
Compatibility: Operates from any 10–18 volt AC or DC power source and controls DC-powered loads up to 250 mA.
-
Contents: One DT-2 detector circuit board and four Opto-Sensors for a normal installation.
-
Detection: Bidirectional operation with circuit memory that keeps the crossing output on until the last car clears.
-
Important detail: On layouts using Command Control, train-direction sensing is defeated and a manual panel switch is required to establish direction before a train reaches the crossing.
For Model Railroad Layouts
The DT-2 detects a train that stops short of the crossing and backs away, then turns the output off. It is suited to modelers building more realistic grade crossing signals and control systems.
