Circuitron DT-1 Bi-Directional Grade Crossing Detector ~ 5201

The CIRCUITRON DT-1 is an advanced, integrated circuit design, detection unit for
grade crossings. The DT-1 operates on a photoelectric principle with tiny Opto-Sensors that mount between the ties.
No modifications to rolling stock are necessary, and the DT-1 will detect powered or unpowered equipment. In
addition, the DT-1 incorporates track polarity detection for bi-directional applications and will provide fully automatic
operation for all scales utilizing 2 rail DC operation. The DT-1 utilizes four Opto-Sensors, two for each direction of
travel. The DT-1 can also provide bi-directional operation for AC or carrier control track power, however, the train
direction must be manually set from the panel. The DT-1 will operate off a wide range of supply voltages between
10 and 18 volts AC or DC. The output terminal on the DT-1 provides a connection to ground (-) when the train is
detected. The output can control any DC powered device with a current draw of 250 ma. or less. The DT-1 does
not include crossbuck flashing circuitry. A CIRCUITRON FL-2 or FL-3 should be used along with the DT-1 for a
complete installation. NOTE: The DT-1 output will be on whenever one of the two Opto-Sensors in the direction of
travel are covered. Short trains falling between sensors will not be detected. If you run many short trains or single
locomotives, use a Circuitron DT-2 instead.
