Woodward 5458-051 Linknet Digital I/O Module Brand New

Product Description

The Woodward 5458-051 LINKnet Digital I/O Module is a distributed input/output node engineered for use in Woodward LINKnet architectures. It enables reliable remote acquisition and control of digital signals when deployed with NetCon and compatible Woodward controllers.

Designed for modular expansion, the 5458-051 operates as an addressable field I/O device on a LINKnet communication trunk, significantly reducing controller cabinet wiring while maintaining deterministic communication and high system availability. Its robust construction and flexible addressing make it suitable for continuous-duty industrial environments where reliability and maintainability are critical.

System Architecture & Communication

The 5458-051 integrates directly into Woodward’s LINKnet distributed I/O network using a single twisted-pair communication cable. Each module functions as an independent node, allowing scalable system layouts and simplified installation across wide physical distances.

LINKnet supports multiple trunks per controller, enabling large I/O counts without compromising performance or diagnostic visibility.

Key Functional Capabilities

• Remote digital input and output processing over LINKnet
• Hardware-based node addressing via onboard rotary switches
• Deterministic communication suitable for real-time control
• Modular expansion without controller hardware modification
• Designed for auxiliary systems and non-primary turbine control

FAQ

Q: Is the 5458-051 used for primary turbine safety functions? A: No. This module is intended for auxiliary and general control functions rather than primary turbine protection or safety shutdown loops.

Q: How is the module address configured? A: Addressing is set locally using onboard hardware rotary switches, eliminating the need for software-based node configuration during installation.

Q: Can multiple LINKnet trunks be used on one controller? A: Yes. LINKnet controllers support multiple trunks, each capable of hosting up to 60 modules.
