Woodward 5463-787 505 Digital Turbine Controller

Product Description

The Woodward 5463-787 is a microprocessor-based 505 series digital turbine controller for single-valve steam turbines. It supports single extraction / admission and split-range actuator configurations, integrates speed governing, load control and protection logic. Equipped with front panel OCP including 2-line 24-character LCD and keypad, it allows local parameter setup, monitoring and alarm checking. It is widely used as spare part for power plant turbine control cabinets.

Features

• 24VDC power supply, approx 1A power consumption, operating temperature range -20℃ ~ +60℃
• Rich I/O: 8 discrete outputs, 6 analog outputs, 2 dedicated actuator drive outputs
• Supports Modbus, RS232 / RS422 serial communication for HMI and upper system connection
• Dual control modes: isochronous (constant speed) and droop (load sharing) regulation
• Built-in overspeed protection, startup ramp, speed/load limit and fault diagnostic functions
• Front panel LCD and keypad for local operation, status LED indicators for fault diagnosis
• Accepts 4-20mA / 1-5V setpoint signals from external control systems
• Industrial anti-vibration and EMC design, suitable for turbine room harsh environment

Application Scenarios

• Industrial single-valve steam turbine speed and load governing control
• Cogeneration power plant, sugar mill, chemical plant turbine generator unit
• Single extraction / admission steam turbine and split-range actuator control
• Turbine control system retrofit, spare parts replacement and maintenance
• Generator island operation and grid parallel load sharing control
