WOODWARD 8200-1330 505DR Dual-Redundant Steam Turbine Controller
Product Brief Description
Woodward 8200-1330 is the 505DR dual-redundant digital turbine controller for single-valve steam turbines, powered by 18–36 Vdc low voltage DC supply. This panel-mounted governor features two independent control channels with automatic bumpless channel switchover if the active channel fails. It delivers high-reliability speed regulation, generator load control, turbine sequence and protection logic, integrated HMI display and keypad, plus Ethernet and serial Modbus communication interfaces for DCS integration. It is widely stocked as spare part for critical steam turbine packages requiring high availability.
Product Features & Functions
- Dual redundant control architecture with two independent controller channels, automatic fault switching
- Precise speed governing, base load control and bumpless transfer between speed and load modes
- Configurable auto startup sequence, warm/hot start ramp profiles and critical speed avoidance
- Overspeed monitoring, loss-of-speed detection, alarms and configurable turbine trip interlocks
- Dual actuator drive outputs supporting split-range valve control for steam governor valves
- Low voltage DC power input: 18–36 Vdc, designed for critical power supply environments
- Front panel HMI, keypad and multilingual display for local operation and parameter viewing
- Ethernet and Modbus RTU serial ports for DCS, PLC and DSLC-2 synchronizer connection
- Event recorder captures alarms, trips and trending data for post-fault root cause analysis
- Built-in continuous cross-channel health checking and diagnostic reporting for both channels
Application Scenarios
- Critical single-valve steam turbine generator sets with high availability requirements
- Turbine-driven compressors, pumps and fans for continuous mechanical drive service
- Cogeneration CHP plants and captive power stations where downtime must be minimized
- Refinery, chemical and pulp & paper industrial process steam turbines
- High-reliability control retrofit, spare replacement and planned outage maintenance
FAQ
Q: What is the difference between 505DR and 505XT?
A: 505DR provides dual redundant control channels for fault tolerant operation. 505XT is simplex non-redundant controller for standard applications.
Q: What power supply for 8200-1330?
A: It uses low voltage DC 18–36 Vdc. The AC/DC redundant version is part number 8200-1331.
Q: What happens if the active channel fails?
A: The controller automatically switches to standby channel with bumpless transfer, keeping turbine control running without shutdown.
Q: Does 505DR overspeed monitor count as SIL safety protection?
A: No. The built-in overspeed monitoring is for control. Independent SIL-rated overspeed trip hardware must be installed for safety functions.
Q: Are refurbished 8200-1330 spare controllers available?
A: Refurbished spare units are available. Both channels are fully tested including switchover logic, I/O and communication before shipment.
