Measurex 05348100 Data Freeway Controller - 8 MHz Honeywell Type I

The Measurex 05348100 is a legacy Data Freeway Controller board designed for industrial process control applications, particularly in paper, plastics, and metals manufacturing industries. Originally developed by Measurex Corporation (acquired by Honeywell in 1997), this Type I controller operates at 8 MHz and facilitates high-speed data communication and control within Measurex's distributed control systems. Key features include robust multiprocessing capabilities, real-time data handling, and integration with sensors and actuators for precise process monitoring. Advantages over similar vintage controllers include reliable performance in harsh industrial environments, modular design for easy integration into existing Measurex frameworks, and support for legacy protocols that ensure compatibility with older Honeywell systems. However, drawbacks include obsolescence, limited availability of parts, and lack of modern connectivity options like Ethernet, making it suitable primarily for maintaining legacy installations rather than new deployments. Applications span quality control in manufacturing lines, where it excels in data acquisition and freeway bus communications. Condition analysis from images shows it as used/surplus, with no visible damage, wrapped in plastic, and including a tag with P/N 05348100. Estimated market value is based on surplus sales data for similar obsolete boards.
