Medha’s Multi Section Digital Axle Counter (MSDAC) is a CENELEC SIL4 Certified advanced solution designed to overcome the limitations of traditional track circuits in challenging conditions such as waterlogged or flooded areas, metal bridges, extended block sections, yards with poor shunting lines, high electro-magnetic interference environments, tunnels, high-temperature regions, and complex, large stations.

Key Features

1. 2oo3 Architecture: Utilizes a robust “Two-out-of-Three” design for enhanced fault tolerance and reliability.
2. Comprehensive Monitoring: Capable of evaluating up to 40 detection points and tracking occupancy for up to 39 sections simultaneously.
3. Versatile Application: Ideal for stations and yard areas, monitoring all track sections, including main lines, loop lines, platform lines, goods lines, stabling lines, common lines, point zones, and sidings.
4. Wheel diameters: 380 mm to 1092 mm
5. Wheel speed: Up to 300 km/h
6. Sleepers: Wood, Steel, Concrete, Composite
7. Ingress protection: IP68

Configurations

1. 1DP-1S: Single detection point, single section – typically used for sidings.
2. 2DP-1S: Two detection points, single section – suitable for straight-line sections.
3. 3DP-1S: Three detection points, single section – designed for point zones.
4. 3DP-2S/AS: Three detection points, configured for two consecutive sections or auto-sections in straight-line layouts.
5. Multiple Detection Points – Single Section: Ladder configurations for complex track layouts.
6. Consecutive Single Sections: Ideal for monitoring straight-line segments and other specific scenarios.
