Product Overview

The Foxboro RH924WA functions as a high-speed Fiber Optic Network Adapter specifically designed for the FCP280 (Field Control Processor 280) within the I/A Series and Foxboro Evo architectures. This 100% Brand New original module facilitates long-distance, noise-immune data transmission between the control processor and the wider DCS mesh network. By utilizing fiber optic media, the RH924WA eliminates electromagnetic interference (EMI) risks and ground loops, ensuring deterministic communication in massive industrial complexes such as refineries, power plants, and offshore platforms.

Engineering Advantages

• Total EMI/RFI Immunity: The RH924WA utilizes optical signals to transmit control data. This inherent immunity to electrical noise makes it the ideal choice for environments with heavy motor activity, high-voltage switchgear, or frequent lightning transients that would compromise copper-based Ethernet.

• Extended Communication Reach: Fiber optic connectivity allows the FCP280 to interface with remote I/O subsystems or operator stations located kilometers away. This removes the distance limitations of standard copper cabling while maintaining high-speed data integrity.

• Native Redundancy Support: The module integrates seamlessly into fault-tolerant DCS configurations. When paired with a secondary RH924WA, the system ensures uninterrupted network visibility even if a single fiber run or adapter encounters a physical break.

• Deterministic Data Throughput: Dedicated onboard processing manages the overhead of fiber optic signal conversion. This ensures that the FCP280 receives time-stamped process data without the jitter or latency common in standard enterprise-grade network converters.

• Simplified Rack Integration: Designed as a plug-in module, the RH924WA seats directly into FCP280-compatible baseplates. This modularity allows for rapid hardware replacement and minimizes the "spaghetti wiring" often found in traditional networking setups.

FAQs

• Can I mix the RH924WA with copper-based adapters in the same rack?

  The RH924WA is designed for the FCP280's fiber-specific communication paths. While the DCS can support multiple media types, ensure your baseplate and switch infrastructure support the fiber optic conversion protocols required by this specific module.

• What type of fiber connectors does the RH924WA use?

  The RH924WA typically utilizes standard industrial fiber connectors (verify specific sub-model for LC vs. ST/SC). Always ensure your fiber patch cables match the module's optical port specifications for decibel loss and wavelength compatibility.

• Is this module hot-swappable?

  Yes. Provided your control system uses a redundant network architecture, you can replace a faulty RH924WA while the FCP280 continues to communicate through the secondary network path.
