5501-470

WOODWARD 5501‑470 is a high‑performance digital turbine/generator control processor module under the MicroNet series, manufactured by Woodward, USA. It serves as the core control unit for gas turbines, steam turbines, diesel/gas‑fired generator sets, delivering high‑precision speed regulation, load control, unit synchronization and multi‑unit parallel load sharing. Certified for marine and power‑critical applications, it meets SIL2 safety requirements for continuous, reliable operation in harsh industrial environments.

Description

Product Details

This module integrates advanced PID adaptive control algorithms and 32‑bit high‑speed processing, realizing closed‑loop regulation of rotating speed, power, pressure and fuel supply. It supports multi‑fuel control (diesel, natural gas, dual‑fuel) and networking of up to 16 units for load balancing with ±1% precision.
It features multiple communication interfaces (RS‑232/485, Ethernet, Modbus TCP/RTU) to connect with DCS, PLC and SCADA systems for remote monitoring and parameter configuration. Equipped with built‑in self‑diagnosis, fault alarm and over‑temperature/over‑current protection functions, it adopts plug‑in modular hot‑swap design, compatible with Woodward MicroNet control chassis for easy installation and maintenance.
Industrial‑grade hardware ensures strong anti‑EMI, anti‑vibration (15g), wide temperature adaptability (-40℃~+85℃), suitable for thermal power plants, gas‑fired power stations, petrochemical plants, marine power systems and offshore platforms.
