Circuitron 800-5203 DT-3 Grade Crossing Detector Single Direction

DT-3 Grade Crossing Detector Single Direction

Details:

The Circuitron DT-3 Single Direction Grade Crossing Detection Circuit is a versatile optical train detection system designed to provide reliable and realistic grade crossing operation on virtually any model railway. Using Circuitron's proven opto-electronic detection technology, the DT-3 accurately detects approaching trains without requiring any modifications to locomotives, coaches or freight cars.

Capable of handling anything from a single locomotive to a long freight consist, the DT-3 delivers dependable crossing activation regardless of train length. Its non-contact optical sensing system ensures smooth operation while maintaining complete compatibility with existing rolling stock fleets, making installation simple and unobtrusive.

Unlike many train detection systems, the DT-3 operates completely independently of track power. This allows it to be used on layouts powered by DC, AC or Digital Command Control (DCC) systems, making it an excellent choice for modellers seeking a flexible and future-proof crossing detection solution. Suitable for any scale, the DT-3 can be integrated into a wide range of signalling and automation projects.

The DT-3 can be used to control Circuitron alternating flashers, bell ringers, relays and other automated accessories, making it ideal for creating realistic grade crossing warning systems. Powered by a separate low-voltage supply, the detector remains independent of track conditions and locomotive current draw, ensuring consistent performance across a wide range of operating environments.

The DT-3 is an excellent choice for single-direction approaches to grade crossings, industrial sidings, automated warning systems and train-activated scenic effects, delivering dependable operation and prototype-style functionality across a wide variety of model railway applications.
