This module acts as a critical 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 sends control signals to on‑site actuators, realizing closed‑loop regulation of rotating speed, pressure, flow and unit load.

Designed with industrial‑grade hardware, it features 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. The plug‑in modular structure is compatible with Woodward series control systems, enabling convenient installation, replacement and maintenance. It has wide temperature adaptability and long‑term operational stability for continuous‑running industrial facilities.

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.
