Description
Woodward 8440-1019C
Technical Specifications
- Processor Speed: Increased clock rate for faster algorithm execution.
- Memory: Expanded flash memory for additional data logging and curve points.
- Communication: Enhanced RS-485 transceiver with improved common-mode rejection.
- Power Consumption: Optimized power management reducing internal heat generation.
- Firmware: Supports latest generation Woodward control strategies.
Functional Features
- Advanced Filtering: Software-configurable digital filters for noisy MPU signals.
- Event Sequencer: Programmable start-up and shutdown sequences with timed outputs.
- Trend Recording: Captures high-resolution waveform data prior to and during fault events.
- Password Protection: Multi-level security to prevent unauthorized parameter changes.
Application Scenarios
Ideal for retrofitting older governing systems or new builds requiring high-reliability digital control.
Performance Parameters
- Resolution: 16-bit analog-to-digital conversion for superior signal fidelity.
- Drift: Less than 0.01% per degree C temperature change.
- EMC Compliance: Meets IEC 61000-4 standards for industrial immunity.
Material Composition
Utilizes lead-free solder and RoHS-compliant components. Board substrate is high-Tg FR4 for improved thermal stability.
Structural Characteristics
- Form Factor: Pin-compatible with 8440-1019 for drop-in replacement.
- Labeling: Clear silkscreen identification for the “C” revision to prevent mix-ups.
- Thermal Pads: Integrated heat spreaders on high-power ICs.
Working Principle
Operates identically to the base 8440-1019 but leverages increased processing headroom to run more complex control algorithms and handle higher I/O counts without sacrificing response time.
Installation Requirements
- Verify backplane firmware is compatible with the “C” revision before installation.
- Update system configuration software to the latest version to recognize new features.
- Follow standard ESD and mechanical installation procedures.
Usage Precautions
- Do not mix “C” revision boards with older revisions in redundant configurations unless explicitly approved.
- Backup existing parameters before installing the upgraded board.
- Allow the board to complete its self-test sequence before enabling engine start.
