WOODWARD 505XT 8200-1311 Steam Turbine Digital Controller

Product Brief Description

Woodward 505XT 8200-1311 is a panel-mounted digital turbine controller designed for extraction/admission steam turbines. It is the upgraded drop-in replacement for the legacy 505E governor. This all-in-one unit integrates speed regulation, extraction pressure control, generator load control and turbine protection logic. It supports AC/DC universal power supply, on-screen HMI and Ethernet/serial communication for DCS connection, widely used as spare part for industrial steam turbine packages.

Product Features & Functions

• Speed governing, load control and extraction/admission pressure regulation for steam turbines
• Built-in ratio limiter algorithm to decouple speed and extraction pressure control
• Bumpless mode transfer between speed, pressure and base load control
• Auto / manual turbine startup sequence with warm/hot start ramp profiles
• Overspeed detection, speed fault, input loss and configurable turbine trip protection
• Front panel HMI display, local keypad for parameter setup and real-time monitoring
• Universal AC/DC power input, works with 88–264 Vac or 90–150 Vdc
• Ethernet and Modbus RTU communication interfaces for upper DCS or PLC systems
• High-resolution event recorder to store trip and alarm history for post-fault analysis
• Supports single valve and split-range actuator drive outputs

Application Scenarios

• Single extraction / admission industrial steam turbine generator sets
• Turbine-driven compressors, pumps, fans and turbo-expanders
• Cogeneration, CHP plants and captive power stations
• Chemical, pulp & paper, refinery and sugar mill process turbines
• Retrofit upgrade replacing older Woodward 505E turbine governors
