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 instructions to on‑site actuators, realizing closed‑loop regulation of rotating speed, pressure, flow and unit load.

Built with industrial‑grade hardware, it has strong anti‑electromagnetic interference and anti‑vibration performance. It supports standard industrial signals including 4‑20 mA and 0‑10 V with high‑precision signal acquisition and output. The plug‑in modular structure is compatible with Woodward series control systems for convenient installation, replacement and maintenance. It features wide temperature adaptability and long‑term stability, suitable for long‑term continuous operation.

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