Product Overview
Woodward 5501‑372 REV‑B triplex high‑density analog I/O module is designed for Woodward MicroNet TMR fault‑tolerant control system. It performs analog signal acquisition and control output for turbine units. Adopts 2‑out‑of‑3 voting triplex architecture, system keeps running under single‑point fault. It collects pressure, temperature and speed sensor signals, outputs 4‑20mA /0‑10V signals to drive servo actuators, with on‑board self‑diagnosis and galvanic isolation. Widely used as replacement spare parts for high‑reliability turbine control in power plant and offshore oil‑gas site。
