Product Overview

The Woodward 8901-457 (Part Number 8901-457) is a precision Current Sensing Module engineered for use with the Woodward 723PLUS Digital Control system. This module converts high-level current signals from generators or motors into low-voltage analog signals for accurate monitoring and control. Essential for load sharing, droop operation, and generator protection, the 8901-457 ensures reliable and stable operation across diesel engines, gas turbines, and generator sets.

Its compact and rugged design allows for installation in harsh industrial environments, providing galvanic isolation, vibration resistance, and integration flexibility for demanding control applications.

Performance Characteristics

Precise Load Monitoring

• Accurate Signal Conversion: Converts 1A or 5A CT outputs into precise millivolt signals suitable for 723PLUS inputs.

• Balanced Load Sharing: Supports multiple generator sets operating in parallel by providing exact current measurements to distribute kW loads evenly.

Enhanced System Responsiveness

• Real-Time Feedback: High-speed processing allows governors to respond instantly to load changes, preventing frequency fluctuations or engine stalls.

• Low Burden Design: Maintains accuracy of primary Current Transformers without introducing significant impedance.

Industrial-Grade Reliability

• Galvanic Isolation: Electrically separates high-power generator circuits from sensitive control electronics, protecting the 723PLUS from transients.

• Vibration and Shock Resistant: Engineered to withstand vibration-heavy environments and meet rigorous industrial standards.

Seamless Integration

• Compact Footprint: Suitable for DIN-rail or chassis mounting.

• Plug-and-Play Compatibility: Factory-calibrated for 723PLUS systems, eliminating complex setup or scaling adjustments.
