Key Features & Advantages
The **Woodward 5484-735** is a ruggedized digital speed controller for industrial engines and turbines. Features dual-processor redundancy with <20 ms failover for uninterrupted operation. Integrated PID algorithms optimize speed regulation (±0.25% setpoint accuracy) under variable load conditions. Built-in diagnostics monitor overspeed events, sensor faults, and actuator health. Compatible with Woodward’s ToolKit™ software for real-time tuning, datalogging, and waveform analysis.
5484-735
Supports ISO 8528-5 transient response standards. MIL-STD-810G compliant for shock/vibration resistance. Conformal coating option available for harsh environments (salt fog, humidity). Hot-swappable design minimizes downtime during maintenance.
Applications
Critical in **diesel/gas power gensets** for frequency stabilization. **Oil & gas** platforms use it for compressor drive control. **Marine propulsion systems** rely on its CANopen integration. **Pipeline pumping stations** deploy it for turbine speed regulation. Also applied in **cogeneration plants** and **emergency backup systems** requiring ISO 21789 compliance.
