The Kelvin Hughes 7097808 is the central processing unit (CPU) board for the Water Track Unit (WTU) Assembly, a critical component in marine speed log systems. Engineered for reliability in demanding maritime environments, this board processes sensor data to provide accurate vessel speed information through the water. It serves as a direct replacement or spare part for specific Kelvin Hughes speed log models, ensuring continued system performance and navigational safety. The board integrates multiple interface options, onboard power regulation, and diagnostic features for seamless integration and maintenance within the WTU chassis.
