Woodward 5501-365 Governor MPU I/O Module

Product Introduction

The Woodward 5501-365 Governor MPU I/O Module is a highly specialized input/output interface module designed for precision speed sensing and signal processing in governor control systems. This module supports Magnetic Pickup Units (MPUs), which are essential for detecting rotating shaft speed in engines and turbines. Acting as a crucial link between field-mounted MPUs and the digital control unit, the 5501-365 processes frequency-based speed signals and transmits real-time input to the central governor controller.

This I/O module is part of Woodward’s robust digital governor series and is engineered to operate reliably in demanding environments. It enhances the overall system’s ability to measure, regulate, and respond to rapid changes in engine or turbine speed. It supports a variety of control applications where MPU-based speed measurement is critical for performance and safety.

Designed for easy integration into Woodward’s control platforms such as NetCon™ and MicroNet™, the 5501-365 ensures high signal integrity, robust fault detection, and accurate speed feedback—all crucial for mission-critical industrial control systems.
