Description
Woodward 5463-786
Technical Specifications
- Processor: High-speed DSP or RISC architecture.
- Memory: Flash for program storage, RAM for real-time data.
- Communication: Backplane bus and external serial/Ethernet ports.
- Watchdog: Hardware watchdog timer for fail-safe operation.
Functional Features
- Real-Time Execution: Deterministic scan rates for critical turbine control.
- Programmable Logic: Supports ladder logic, function blocks, or structured text.
- Data Logging: Records trip events and operational trends.
- Self-Diagnostics: Continuous self-test of CPU, memory, and I/O.
Application Scenarios
Core controller in steam turbine governors, gas turbine control panels, and engine management systems.
Performance Parameters
- Scan Time: <5 ms for basic control loops.
- MTBF: >100,000 hours.
Material Composition
Multi-layer PCB with surface-mount technology. Gold-plated backplane connectors. Battery-backed RAM for data retention.
Structural Characteristics
Standard card size for the specific Woodward chassis. Front panel has run/fault LEDs and a mini-USB or serial port for local configuration.
Working Principle
Fetches instructions from memory, reads I/O status, executes control algorithms, and updates outputs in a continuous, deterministic loop.
Installation Requirements
Set address jumpers/DIP switches to match the system configuration. Insert into the correct slot. Secure the ejector levers.
Usage Precautions
- Remove the backup battery before disposing of the card.
- Do not remove the card while power is applied.
- Keep firmware versions consistent across redundant processors.
