Product Advantages and Features
Ruggedized for Industrial Environments: Wide operating temperature range allows for installation in harsh turbine environments where standard screens would fail.
Triple Modular Redundancy (TMR) Support: Engineered to interface seamlessly with Woodward’s high-availability 2-out-of-3 voting architectures.
Clear Alphanumeric Feedback: The high-contrast display ensures that critical fault codes and system status messages are readable even in low-light conditions.
Compact Footprint: Ideal for panel mounting in tight spaces or on-engine control cabinets.
Longevity: Although categorized as a legacy component, it is widely supported in “Lifecycle” service programs for aging infrastructure.
