Woodward 3522‑1004 Digital Speed Controller | Woodward Governor Control Module

Description

Product Overview

Woodward 3522‑1004 digital speed controller is designed for closed‑loop speed regulation of engines and turbines. It collects speed, pressure and temperature signals, outputs driving signals to actuators, supports isochronous & droop load‑sharing for parallel generator sets. Equipped with RS232/RS485 Modbus RTU interface for DCS / SCADA integration. Wide operating temperature makes it reliable for power plant, marine and oil‑gas field harsh conditions.
