Overview

The Woodward 5441-419 ISO Relay Interface Module is engineered to bridge control logic and high-power field devices in industrial automation systems. It features 16 independent relay channels, each equipped with 2 Form C (SPDT) contacts, allowing flexible control of motors, solenoids, alarms, and other actuators.

Moreover, the module is designed for electrical isolation, ensuring safe and reliable signal transmission between low-voltage control circuits and high-voltage loads. Its robust construction and CE/UL certifications make it suitable for harsh environments, including power generation, marine, and process control applications. In addition to switching capabilities, the module includes LED indicators for status monitoring and supports DIN rail or panel mounting for easy integration.

Therefore, the 5441-419 is widely used in systems requiring fast response, high-current handling, and secure relay interfacing.

Technical Data

Typical Applications

• Turbine and Engine Control: Interfaces with actuators and sensors for fuel, speed, and temperature regulation.

• Process Automation: Controls pumps, valves, and alarms in chemical and water treatment plants.

• Power Generation: Manages switching operations in generator protection and load control systems.

• Marine Systems: Supports propulsion and auxiliary control in shipboard automation.

• Industrial Machinery: Enables relay-based control in manufacturing and robotic systems.

For instance, in a turbine control panel, the 5441-419 can activate cooling fans and trip relays based on PLC logic. In addition, its opto-isolated design protects sensitive electronics from electrical noise and transient voltages.
