Product Description: Woodward 5461-655 Final Drive Module

Product Model: 5461-655

Brand: Woodward

Product Type: Final Drive Module / Power Output Module 

I. Product Overview

The Woodward 5461-655 is a high-power, high-current drive module, serving as the power amplification interface between the control system (such as 505, 723 speed regulators) and the field actuators (such as servo valves, electro-hydraulic converters, proportional valves). It converts weak control signals into strong drive currents/voltages, directly driving high-power actuators, and is a key link in the "connection of 'brain' and 'limbs'" in industrial power control.
