Description
Woodward 5501-376
Technical Specifications:
- Brand: Woodward
- Model: 5501-376
- Product Type: Digital Microprocessor Controller
- Communication Interfaces: RS-232, Ethernet (Modbus protocol)
Functional Features:
- Advanced System Optimization: Supports multiple control modes including isochronous mode for optimal load sharing in multi-unit plants.
- Remote Monitoring: Equipped with Ethernet and RS-232 ports to facilitate remote data acquisition and integration with DCS/PLC systems.
- Critical Speed Avoidance: Incorporates specialized algorithms to automatically bypass critical turbine speeds during startup and shutdown.
Application Scenarios:
Extensively used in turbine generator sets, waste heat recovery systems, oil field drive equipment, and pipeline compressors.
Performance Parameters:
- Contact Inputs: 16 (4 fixed, 12 programmable)
- Analog Inputs: 6 programmable (4-20mA)
- Analog Output: 0-10V DC
Material Composition:
Constructed with high-reliability electronic components housed in a durable, vibration-resistant enclosure.
Structural Features:
Features a compact footprint of 15.2 cm × 5.1 cm × 20.3 cm. The front panel includes an operator control interface with a two-line text display for easy parameter adjustment.
Working Principle:
The microprocessor continuously samples turbine parameters and calculates the precise actuator positioning required to maintain desired speed or load setpoints, outputting analog signals to drive inlet valves.
Installation Requirements:
Must be mounted securely in a control cabinet with proper airflow. Network cables must be properly terminated to prevent communication errors.
Usage Precautions:
Ensure firmware is updated to the latest version. Regularly perform self-diagnostics using the integrated operator panel to maintain system reliability.
