Description

Woodward 5464-473

Technical Specifications

  • Processor Architecture: High-speed 32-bit RISC or DSP architecture.
  • Memory: Non-volatile flash memory for firmware and configuration, RAM for real-time data buffering.
  • Backplane Interface: High-speed digital bus for communication with I/O and communication modules.
  • Watchdog Timer: Hardware-based watchdog for automatic fail-safe recovery in the event of a processor fault.

Functional Features

  • Real-Time Execution: Guarantees deterministic scan times for critical speed, load, and temperature control loops.
  • Advanced Protection: Processes safety-critical logic for overspeed, over-temperature, and vibration shutdowns.
  • Data Logging: Records operational trends and fault events for predictive maintenance.
  • Communication Gateway: Manages data exchange with SCADA, DCS, and local HMIs via multiple protocol options.

Application Scenarios
Core processing card in MicroNet, 5000 Series, or PeakMaster control systems for gas turbines, steam turbines, and large reciprocating engines.

Performance Parameters

  • Scan Rate: Basic control loop execution in under 10 milliseconds.
  • Mean Time Between Failures (MTBF): Exceeds 100,000 hours of continuous operation.

Material Composition
Multi-layer printed circuit board with surface-mount technology. Components are screened for extended industrial temperature ranges. Gold-plated edge connectors ensure reliable backplane contact.

Structural Characteristics
Standard form factor for the target Woodward chassis. Features front-panel LEDs for Run, Fault, and Communication status. Includes a local configuration port (USB or serial).

Working Principle
Continuously polls input modules for process variables, executes the user-defined control logic, and updates output modules. It operates on a deterministic real-time operating system to guarantee response times.

Installation Requirements
Verify the card’s address jumpers or DIP switches match the system configuration before insertion. Seat the card firmly into the backplane and secure the ejector levers.

Usage Precautions

  • Always observe electrostatic discharge (ESD) precautions when handling.
  • Never insert or remove the card while the chassis is powered.
  • Ensure firmware versions are compatible with other cards in the system.
