WOODWARD 5441-629 Product Detailed Description

Product Model: WOODWARD 5441-629

Brand: WOODWARD (Woodward)

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

Generation Time: 2026-05-18 11:15:58

I. Product Overview

WOODWARD 5441-629 is a multi-channel relay output interface module specifically designed for the early NetCon 5000 and MicroNet control systems. As a signal isolation and power amplification unit between the control system and the field equipment, it converts weak electrical control signals into strong electrical switch signals that can directly drive actuators such as solenoid valves and motors. This module is a discontinued model and is currently available in refurbished or spare parts form in the market.

II. Core Functional Characteristics

Multi-channel Relay Output: Provides 16 independent isolated relay output channels.

5A High Current Drive: Each channel has a rated load of 5A @ 250V AC / 30V DC, capable of directly driving most industrial actuators.

Full Electrical Isolation: Electrical isolation of input, output, and power supply, effectively suppressing interference and protecting the main controller.

Channel Status Indication: Each channel is equipped with an independent LED indicator, displaying the output status in real time, facilitating diagnosis.

Standard Rack Installation: Compatible with NetCon/MicroNet standard 12-slot racks, plug-and-play.

Industrial-grade Reliability: Wide temperature and shock-resistant design, suitable for harsh industrial environments such as power plants and petrochemicals.

Hot Swap Compatibility: Supports online insertion and removal, facilitating maintenance and replacement.
