Product Advantages and Features
Advanced Control Algorithms: Built-in logic for three-stage critical speed avoidance, overspeed anticipation, and adaptive PID tuning.
User-Friendly HMI: Large 8.4″ graphical display allows for real-time trending, event logging (alarms/trips), and multi-language support.
Extraction Control: Unlike the standard 505D, the 505XT (8200-1310) is designed for single extraction or admission steam turbines.
Robust Connectivity: Seamlessly integrates with Distributed Control Systems (DCS) via Modbus, facilitating remote monitoring and plant-wide automation.
Field Programmability: Menu-driven software allows for onsite configuration without the need for specialized external programming tools for standard setups.
Application Cases
The Woodward 8200-1310 is widely deployed across various heavy industries:
Power Generation: Synchronizing turbine-driven generators to the grid with precise load sharing.
Petrochemical/Oil & Gas: Controlling large compressors and pumps where extraction steam is used for process heating.
Manufacturing: Managing boiler fans and mechanical drives in pulp and paper or steel mills.
Marine: Propulsion and auxiliary turbine control on large vessels.

Installation and Maintenance
Mounting: Designed for flush-mounting on a control panel. Ensure adequate ventilation to maintain the operating temperature range.
Wiring: Use shielded, twisted-pair cables for low-level signals (MPUs and Analog I/O) to prevent EMI interference. Field wiring should be rated for at least 75°C.
Grounding: Proper chassis grounding is critical to protect the microprocessor from electrostatic discharge (ESD).
Maintenance: Regularly review the “Trip and Alarm” event recorder to identify precursor signs of turbine wear.
The unit features self-diagnostics that monitor CPU health and I/O status.

Unique Product Description
The Woodward 8200-1310 is more than just a governor; it is the “brain” of the steam turbine.
While standard controllers focus merely on speed, the 8200-1310 utilizes a unique PID structure that balances speed, load, and extraction pressure simultaneously.
This “multivariable” approach ensures that even during sudden load changes or process steam fluctuations, the turbine remains stable, preventing costly downtime and equipment stress.
