Product Model: WOODWARD 5441-409

Brand: WOODWARD (Woodward)

Product Type: NetCon 5000 / MicroNet Series 28-channel Relay Interface Module (Relay Interface Module)

Generation Time: 2026-05-18 11:10:33

I. Product Overview

WOODWARD 5441-409 is a high-capacity, multi-channel digital signal isolation and drive module specifically designed for industrial control systems (such as NetCon 5000, MicroNet). Its core function is to convert weak control signals from the control system into strong electrical drive signals for directly controlling external high-power devices (such as solenoids, motors, alarms, circuit breakers, etc.). It provides 28 independent isolated relay output channels, with LED status indication and overcurrent protection, making it a key interface unit connecting the control system to the field actuators.

II. Core Function Characteristics

28-channel Independent Output: Provides 28 fully electrically isolated relay contact outputs, with a maximum drive capacity of 10A per channel.

LED Status Indication: Each channel is equipped with an independent LED indicator, which displays the contact on/off status in real time, facilitating on-site diagnosis.

Full Electrical Isolation: Input / Output / Power supply three-terminal isolation, effectively suppressing interference and protecting the main controller from strong electrical shocks in the field.

High Load Capacity: Supports a wide voltage range of 250V AC / 30V DC, capable of directly driving various industrial loads.

Overcurrent Protection: Built-in channel-level overcurrent / short-circuit protection to prevent external faults from damaging the module and the system.

Hot Swap Design: Supports online insertion and removal, allowing for maintenance and replacement without power interruption, ensuring continuous system operation.

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

Industrial Grade Reliability: Wide temperature operation, strong anti-interference, long-life design, suitable for harsh industrial environments such as power plants, petrochemicals, etc.
