This module acts 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 outputs control instructions to actuators, realizing closed‑loop regulation of rotating speed, pressure, flow and unit load.

With industrial‑grade circuit design, it features excellent 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, enabling easy installation, replacement and maintenance. It has wide temperature adaptability and long‑term stability, suitable for long‑term continuous operation.

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