Functional Overview

The 5441-419 (Model 5441-419) is a high-density, 16-channel relay interface module designed for the Woodward MicroNet and MicroNet Plus control systems. This module serves as a robust isolation barrier between low-level electronic control signals and high-power industrial field devices. By providing sixteen independent electromechanical relay outputs, the 5441-419 enables the control system to command heavy-duty actuators, motor starters, and solenoid valves while maintaining electrical separation between the control and field layers.

Engineered for reliability in demanding environments, the 5441-419 includes integrated diagnostic LEDs for each of its 16 channels, allowing for rapid visual confirmation of relay status. Its compact design and high channel density make it an ideal choice for systems requiring a high volume of isolated relay outputs within a limited footprint.

Field Applications and Fault Isolation

The 5441-419 is frequently deployed in turbine control systems and industrial power management applications. Its SPDT Form C contact arrangement provides maximum flexibility, allowing for both normally open (NO) and normally closed (NC) wiring configurations. The high isolation voltage between channels ensures that a localized fault or voltage spike in one field circuit does not propagate to adjacent channels or sensitive controller electronics, significantly increasing overall system uptime.
