I. Product Overview

WOODWARD 5441-691 is a high-capacity relay output module used in MicroNet and NetCon 5000 control systems. As a dedicated FTM (Field Termination Module), it is specifically designed to drive high-power, high-voltage industrial field loads, providing 16 independent isolated relay outputs to achieve safe and reliable signal isolation and drive between the control system and the on-site high-voltage equipment. This module is a discontinued model, and the market mainly circulates refurbished / spare parts. 

II. Core Functional Characteristics

16 Independent Relay Outputs: Provide 16 fully isolated SPST relay contacts, meeting the requirements of multiple devices and large-scale control.

High Load Driving Capacity: Each contact has a capacity of up to 5A @ 250VAC / 30VDC, capable of directly driving electromagnetic valves, contactors, motor starters, indicator lights, etc., for high-power loads.

Full Electrical Isolation: The output is isolated from the system side at 2500V AC, effectively suppressing on-site interference and protecting the core control system.

Each Channel Independent LED Indicator: Each channel is equipped with an independent LED status indicator light, displaying the contact open/closed status in real time, facilitating quick diagnosis and maintenance.

Standard FTM Design: Adopt MicroNet standard FTM specifications, directly inserted into the system backplane, supporting hot swapping, and facilitating installation and maintenance.

Industrial-grade Reliability: Wide temperature, shock-resistant, dust-proof design, compliant with CE, UL certifications, suitable for harsh industrial environments such as power plants, petrochemicals, metallurgy, etc.
