Overview

The Honeywell 51202971-111 I/O Link Cable is a high-performance industrial cable engineered for distributed control environments. It connects C300 controllers to multiple I/O modules, enabling synchronized data exchange across Honeywell’s Experion PKS and Series 8 platforms.

Moreover, its EMI/RFI-resistant shielding and robust header design ensure signal integrity in harsh conditions, including high vibration and electrical noise. In addition, the cable’s 1.5-meter length and 3-drop configuration make it ideal for compact control cabinets and modular installations.

This cable is widely used in process industries such as oil & gas, chemicals, and power generation, where uninterrupted I/O communication is critical. Therefore, it is a trusted component in high-availability automation architectures.

Technical Data

Typical Applications

• Distributed Control Systems (DCS): Enables reliable communication between C300 controllers and Series 8 I/O modules.

• Process Automation Networks: Used in systems requiring modular I/O connectivity and high signal integrity.

• Industrial Control Cabinets: Ideal for installations with limited space and high EMI exposure.

• System Expansion Projects: Supports additional I/O drops without reconfiguring core controller architecture.

For instance, in a chemical plant, this cable links multiple I/O modules to a central controller, ensuring real-time monitoring and control of temperature, pressure, and flow. In addition, its rugged design minimizes downtime caused by environmental interference.

FAQ
