I. Product Overview

WOODWARD 5437-465 is a LinkNet bus-based distributed field terminal module (Field Terminal Module), designed specifically for remote I/O signal acquisition and control in industrial control systems. As the core distributed I/O unit of Woodward's LinkNet network, it enables high-speed, isolated, and reliable connections between on-site sensors, actuators signals and central control systems (such as 505, MicroNet, NetCon, 5000 series controllers), and is widely used in remote I/O expansion scenarios for steam turbines, compressors, generator sets, and industrial process automation.

The module adopts full isolation, wide temperature range, and high protection design, supports standard DIN rail installation, and has dual communication capabilities of Ethernet and Modbus TCP, achieving integrated signal acquisition, drive, and diagnosis in a distributed control architecture.
