Product Overview

The Woodward 5464-658 REV H is a high-precision digital speed sensing interface designed for industrial engine and turbine control systems. It directly converts raw pulse signals from magnetic pickups (MPUs) or proximity probes into accurate digital speed data, eliminating the need for external signal conditioning.
Supplied as 100% brand new original equipment, this latest REV H version ensures factory-calibrated accuracy and enhanced reliability for critical overspeed protection and governor control loops.

Technical Specifications

Engineering Advantages

• Direct Sensor Interface: Supports both passive MPUs and active proximity probes without external converters.

• Fast Fault Detection: Continuously monitors signal integrity and triggers protection on sensor failure or signal loss.

• Low-Speed Accuracy: High-resolution time-stamping ensures precise measurement during startup and low-speed operation.

• Robust Protection: Per-channel fusing safeguards the system from wiring faults and voltage transients.
