This module serves as a core I/O and signal processing unit for steam turbines, gas turbines and power‑generating equipment. It collects analog and digital signals from field sensors and transmits control commands to on‑site actuators, realizing closed‑loop regulation of rotating speed, pressure, flow and unit load.

Adopting industrial‑grade hardware design, it delivers strong anti‑electromagnetic interference and anti‑vibration performance. It supports standard industrial signals such as 4‑20 mA and 0‑10 V with high‑precision signal acquisition and output. Its plug‑in modular structure is compatible with Woodward series control systems, allowing easy installation, replacement and maintenance. With wide temperature adaptability and long‑term operational stability, it is suitable for long‑term continuous operation.

Typical application fields include thermal power plants, hydropower stations, gas‑fired power generation, petrochemical plants, iron and steel metallurgy, marine power systems and large‑scale pumping stations.
