Providing Switch protection for the worlds rail systems
Wheel DetectorSystem (WDS) brings presence detection to the next level of performance and ease.
Low Power Requirements
8 to 24 VDC operating voltage range• 120 mA current draw for a 3-Detector system
Ease of Installation
Only two components, the Main Module and the Sensor/Bracket assembly
• Sensor/ Bracket assembly bolts to the base of the rail. Eliminates drilling of the rail.
• Sensors can be quickly and easily relocated by unbolting the Bracket and reinstalling in the desired location.
• Spring cage connectors for ease of wire connections and reliability of the connection
• Complete flexibility in the size and geometric lay out of the protected zone
Fail Safe Reliability for Any Failure Mode
• Fails safe in the event of loss of power
• Fails safe in the event of loss of communication or broken/loose wire or connection
• Fails safe in the event of damage to the wheel sensor
• Fails safe in the event of a sensor becoming loose or falling off the rail
Extremely Compact Size
• The Main Module measures 3" x 3" x 1"
• The Wheel Sensor/Bracket is 10" x 10" x 6" tall
• Attaches to rail sizes 90 lbs. and larger
Designed for Use in Rugged Railroad Environments
• Both the Main Module and the Wheel Sensor are totally encapsulated and sealed against contamination and water
• Engineered to operate continuously at the shock and vibration levels encountered in rail applications.
• Operating temperature range is –40°F to +185°F
• No tuning of the components at startup or at any time during operation
• The system automatically compensates for changes in ambient conditions
• Activating special operating characteristics is easily accomplished through a laptop comput- er operating in a Windows environment
• Missed wheel compensation
• Includes both steady state and pulsed outputs to support “Auto-Line” or other functions
• The Main Module will support up to 28 Wheel Sensors
• The Wheel Sensors can be located up to 2,000 feet from the Main Module
• The Wheel Sensors can be wired in a “daisy chain” fashion greatly simplifying cabling requirements
