Foxboro RH924YL Horizontal-Mounted Baseplate Brand New

Product Description

The Foxboro RH924YL is a horizontal-mounted baseplate designed specifically for the FCP280 controller, providing reliable power distribution, redundancy, and communication interfaces. It ensures seamless integration within Foxboro I/A Series distributed control systems, even under demanding industrial conditions. Moreover, its robust construction allows long-term operation in harsh environments, reducing downtime and maintenance costs.

This baseplate supports dual redundant 24 VDC power inputs, enabling uninterrupted operation of the FCP280 CPU. In addition, the onboard fault-tolerant connector allows hot standby switchover in less than 0.5 seconds, ensuring system reliability. The RH924YL also supports EtherMesh ring redundancy and accommodates up to 32 local fieldbus modules, expandable to 128 via FEM100, enhancing network performance and scalability.

Built for flexibility and future-proofing, the RH924YL maintains backward compatibility with the FCP270 baseplate. Its hot-swappable design simplifies maintenance, allowing modules to be replaced within 15 minutes. Engineers benefit from its corrosion-resistant 316L stainless steel construction and industrial-grade vibration tolerance, making it ideal for oil & gas, chemical, power generation, and water treatment facilities.
