Allen-Bradley 8520-OFC Industrial Remote IO Module

Allen-Bradley 8520-OFC Industrial Remote IO Module is a remote I/O device in Rockwell Automation's 8520 product line, designed to relocate input and output points near field devices while remaining connected to the main controller. As part of the remote I/O family, it wires I/O data between field devices and the central control system, enabling scalable I/O expansion across an automation installation. Typical applications include manufacturing lines, packaging equipment, and process systems where distribution of I/O saves wiring and simplifies maintenance. The 8520-OFC model aligns with Rockwell's ecosystem for 8520-series hardware and software, supporting integrated control and diagnostics within an industrial automation setup.
