Industrial fiber link for Foxboro networks – Provides a robust optical connection for I/A Series DCS segments where copper isn’t practical.
EMI immunity and long-distance runs – Fiber typically shrugs off electrical noise and enables longer spans across large facilities.
Designed for cabinet deployment – Compact module form that fits well in control panels with clean cable routing.
Ethernet compatibility – Works within standard IEEE 802.3 Ethernet environments used alongside Foxboro controllers and switches.
Safer plant networking – Optical isolation reduces ground loop issues and transient risks on critical control networks.
Supports redundant architectures – Suitable for dual-path designs to enhance network availability, which many plants prefer for CCR links.
| Brand / Model | FOXBORO RH924WA |
| Product Type | Fiber Optic Network Adapter (industrial) |
| HS Code | 8517.62 (data transmission apparatus) |
| Power Requirements | 24 VDC nominal, typical consumption |
| Operating Temperature | 0 to 60 °C, non-condensing environment recommended |
| Signal I/O Types | Network data over fiber optic; electrical Ethernet for local coupling (where applicable) |
| Communication Interfaces | IEEE 802.3 Ethernet; fiber optic port (commonly 100BASE‑FX); may be paired with 10/100BASE‑TX |
| Fiber Type | Multimode or single-mode (project-dependent); SC or ST connectors are typical in many cases |
| Installation Method | Cabinet mounting (DIN-rail/panel); fiber patch routing with proper bend radius and strain relief |
Note: Interface details (connector type and specific link speed) can vary by sub-variant and network design. We typically verify against the site’s Foxboro DCS topology before shipment.
Process plants using FOXBORO I/A Series or EcoStruxure Foxboro DCS segments that require fiber backbones between cabinets or buildings.
Areas with heavy EMI, VFDs, or high-current equipment where copper Ethernet is unreliable.
Long-haul control room to remote I/O marshalling panels, utility corridors, and substation links.
Oil & gas, refining, chemicals, pharmaceuticals, power generation, water/wastewater—where deterministic and resilient networking is valued.
Reliability under noise – Fiber optic links typically perform better around high-energy equipment and long cable trays.
Compatibility with Foxboro architectures – Designed to sit comfortably in Foxboro network topologies without awkward workarounds.
Lifecycle confidence – Industrial-grade design with straightforward replacement and spares strategy.
Cost control – In many cases, shifting critical legs to fiber reduces downtime from transient faults on copper.
Support – We can help verify fiber type (single-mode vs. multimode), connector standard, and path redundancy before you place the order.
Cabinet environment – Install in a ventilated control cabinet; maintain ambient 0–60 °C and avoid condensation.
Power and grounding – Supply stable 24 VDC; maintain proper cabinet grounding to minimize common-mode noise.
Fiber handling – Respect bend radius, use quality patch cords, and clean connectors (lint-free wipes and appropriate solvent).
Redundancy – Where the DCS design allows, run dual fiber paths in separate routes to improve availability.
Wiring checks – Verify Tx/Rx polarity, connector type (SC/ST), and fiber type (MM/SM) to match plant standards.
Routine maintenance – Periodic port inspection, connector cleaning, and logging link stats; apply firmware updates if the installed variant supports them.
Manufacturer-built to industrial standards; CE compliant in typical deployments
UL/CSA conformity expected for control-cabinet installation
RoHS alignment for restricted substances
Backed by a 365-day warranty from shipment
Industrial fiber patch cords (SC–SC or ST–ST; 62.5/125 µm multimode or OS2 single‑mode depending on site spec)
DIN-rail fiber management trays and labeled bulkhead adapters for clean routing
Industrial Ethernet switches with fiber uplinks for ring or redundant star topologies
