I. Product Overview

WOODWARD 5441-419 is a 16-channel, high-load, fully isolated relay output interface module specifically designed for Woodward NetCon 5000 and MicroNet control systems. As a bridge between the control system and the field actuators, it converts weak electrical control signals into 10A high-capacity strong electrical switch signals, featuring Form C (double-pole double-throw) contacts and full electrical isolation. It is suitable for critical control circuits that require high driving capability and safety isolation. 

II. Core Functional Characteristics

16-channel isolated output: Provides 16 independent relay channels with complete electrical isolation.

Form C contacts (SPDT): Each channel has a single-pole double-throw contact (1 normally open + 1 normally closed), offering more flexible control logic.

High load driving: Single channel can handle 10A @ 250V AC / 30V DC, capable of directly driving high-power solenoid valves, motors, and contactors.

Full electrical isolation: Input / Output / Power supply three-terminal isolation (2500V AC), effectively suppressing interference and protecting the control system.

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

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

Hot-swappable design: Supports online insertion and removal during system operation, enabling maintenance without system downtime.

Standard rack installation: Compatible with NetCon/MicroNet standard 12-slot rack (5439-861).

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