Product Description: Woodward 5461-651 Analog Output Module

Product Model: 5461-651

Brand: Woodward

Product Type: Industrial-grade Analog Output Module

I. Product Overview

The Woodward 5461-651 is a dedicated high-precision analog signal output module within the 5461 series. Its core function is to convert the digital control signals from systems such as MicroNet, NetCon, 505/723, and drive them into standard 4-20mA current or 0-10V voltage analog signals for precise control of servo valves, electro-hydraulic actuators, frequency converters, recorders, and various on-site regulating instruments. It is specifically designed for closed-loop control circuits of rotating machinery such as gas turbines, steam turbines, and engines, serving as a key interface connecting digital controllers with hydraulic/electrical actuators.
