DT-5 Detection Circuit Simple Circuit

DT-5 Detection Circuit Simple Circuit

Details:

The Circuitron DT-5 is an expansion detection module designed to extend multi-track grade crossing systems in conjunction with Circuitron’s GA-1 controller and other compatible flasher units. It provides additional optical detection capability for layouts featuring more than one track at a crossing, ensuring reliable train sensing across complex railway configurations.

Using Circuitron’s proven Opto-Sensor technology, the DT-5 detects rolling stock whenever a sensor is shaded by a passing train. This allows it to accurately trigger crossing logic and signal systems without requiring any modifications to locomotives or rolling stock. The module is intended to complement existing GA-1 installations, enabling consistent detection across additional tracks within the same crossing environment.

The DT-5 is designed for use with 10V–18V AC or DC power supplies and features adjustable sensitivity to accommodate different ambient lighting conditions. It is suitable for use with a wide range of Circuitron crossing flashers and control systems, providing flexible integration into both simple and advanced layout automation setups.

The DT-5 is ideal for modellers expanding existing grade crossing installations or building complex multi-track crossings. It ensures that each additional track is properly monitored, improving the realism and reliability of automated crossing operations. Sensitivity adjustment allows tuning for different lighting environments, although it is not intended for extremely low-light conditions.
