Description
Woodward 9905-992
Technical Specifications
- Product Type: Electronic Control / Input Module.
- Series: Woodward 9905 Series.
- Signal Processing: Conditioned inputs for speed, temperature, or pressure.
- Communication: Backplane interface for system integration.
Functional Features
- Signal Conditioning: Filters and amplifies raw sensor signals to ensure accurate processing by the main controller.
- Logic Execution: Executes specific control algorithms or safety interlocks.
- System Integration: Seamlessly communicates with other modules in the 9905/9907 series ecosystem.
- Diagnostic Capabilities: Provides fault detection and reporting for connected sensors and internal circuits.
Application Scenarios
Used in industrial gas turbines, steam turbines, and large reciprocating engines as part of a comprehensive digital control and protection system.
Performance Parameters
- Signal Accuracy: High-precision signal processing with minimal latency.
- Reliability: High Mean Time Between Failures (MTBF) for continuous industrial operation.
- Noise Immunity: Excellent rejection of electrical noise in harsh industrial environments.
Material Composition
Constructed with industrial-grade printed circuit boards (PCBs) featuring multi-layer routing for signal integrity. Components are selected for long-term stability and thermal endurance.
Structural Characteristics
Standard modular form factor with precision edge connectors or backplane pins. Features status LEDs and test points for easy troubleshooting and maintenance.
Working Principle
Receives raw analog or digital signals from field sensors, conditions them to standard levels, and passes the processed data to the central control processor. It may also execute local logic to trigger alarms or shutdowns if parameters exceed safe limits.
Installation Requirements
Ensure the module is fully seated in its designated slot on the backplane. Verify that all connector pins are straight and undamaged before insertion.
Usage Precautions
- Never insert or remove the module while the system is powered on (unless hot-swappable).
- Keep firmware and configuration software up to date.
- Refer to the specific 9905-992 manual for exact pinout and signal specifications.
