WOODWARD 5441-661 Product Detailed Description

Product Model: WOODWARD 5441-661

Brand: WOODWARD (Woodward)

Product Type: NetCon 5000 / MicroNet Series 10A Relay Interface Module (Relay Interface Module)

Generation Time: 2026-05-18 11:23:52

I. Product Overview

WOODWARD 5441-661 is a high-power isolated relay output interface module for the NetCon 5000 and MicroNet control systems. As a signal amplifier and isolation unit of the control system, it is specifically designed to drive large-power field devices and provides stronger load capacity than the standard 5A module. This module is a discontinued model, and the market mainly circulates refurbished / spare parts. 

II. Core Functional Characteristics

High power output: Provide 16 independent and electrically isolated relay output channels, with each channel having a rated current of 10A.

Strong drive capability: Contact capacity 10A @ 250V AC / 30V DC, capable of directly driving large-power solenoid valves, motors, contactors.

Full isolation design: Input, output, and power supply are fully isolated, effectively suppressing common-mode interference and protecting the main controller's safety.

Channel status indication: Each channel is equipped with an independent LED indicator, displaying the output on/off status in real time, facilitating on-site diagnosis.

Standard rack installation: Compatible with NetCon/MicroNet standard 12-slot rack, supports hot swapping, plug-and-play, and convenient maintenance.

Industrial-grade reliability: Wide temperature range, shock resistance, dustproof design, suitable for harsh industrial environments such as power plants, petrochemicals, and metallurgy.
