Foxboro RH928AW Fieldbus Termination Cable – Industrial Process Solution

Technical Overview & First Impression

From the perspective of an Industrial Solution Architect, few components are as quietly critical to a distributed control system as the interconnect cable that binds field I/O to the control processor. The Foxboro RH928AW is precisely that component — a purpose-engineered Fieldbus Termination Cable designed to establish a high-integrity communication link between 200 Series Fieldbus modules and the FCP280 Field Control Processor or 200 Series baseplates within the Foxboro I/A Series DCS architecture. In Process Control environments where signal fidelity is non-negotiable, the Foxboro RH928AW delivers the shielded, low-noise pathway that keeps your DCS Hardware performing at specification.

What distinguishes this cable from generic alternatives is its engineered compatibility with the Foxboro I/A Series Fieldbus ecosystem. The RH928AW is not a universal cable adapted to fit — it is a factory-matched component that preserves the electrical characteristics required by the 200 Series Fieldbus module interface. For facilities managing Legacy Components in aging DCS installations, this level of OEM precision eliminates the risk of signal degradation, ground loops, or protocol timing errors that can arise from non-original substitutes. Its Fieldbus-compliant construction also ensures seamless integration with FOUNDATION Fieldbus H1 communication layers, maintaining the deterministic data exchange that modern process automation demands.

Original stock of the Foxboro RH928AW is increasingly scarce as the I/A Series platform matures. Plants that have not secured adequate maintenance inventory face extended downtime when this cable fails — a risk that is entirely avoidable. Our supply chain maintains Factory Sealed units sourced directly from authorized channels, giving your maintenance team access to genuine parts without compromise.

Key Technical Highlights

OEM-Matched Interface: Engineered specifically for 200 Series Fieldbus modules and FCP280 Field Control Processors — no adaptation required.
Shielded Construction for Stability: Multi-layer shielding suppresses electromagnetic interference in high-noise industrial environments, ensuring reliable Fieldbus signal transmission.
FOUNDATION Fieldbus H1 Compatible: Supports deterministic, high-speed communication between field devices and the Distributed Control System backbone.
Redundancy-Ready Architecture: Supports dual-path configurations for high-availability DCS Hardware setups where uninterrupted process control is mandatory.
Factory Sealed Condition: Every unit ships in original manufacturer packaging, preserving connector integrity and cable insulation from storage to installation.
Drop-In Replacement: Identical form, fit, and function to the original — minimizing commissioning time during emergency repair scenarios.

Vertical Industry Applications

Petrochemical & Refining: In continuous process plants, an unplanned DCS Hardware failure can halt production worth tens of thousands of dollars per hour. The Foxboro RH928AW provides the reliable Fieldbus link that keeps FCP280 processors communicating with field I/O, reducing the risk of unscheduled shutdowns in distillation, cracking, and blending units.

Oil & Gas Upstream/Midstream: Remote wellhead and pipeline SCADA systems built on Foxboro I/A Series architecture depend on Legacy Components that are no longer in active production. Maintaining a stock of RH928AW cables ensures that Fieldbus communication paths remain intact across geographically dispersed installations.

Power Generation: Turbine control and boiler management systems integrated with Foxboro DCS require uninterrupted Fieldbus connectivity. A failed termination cable in this environment is a Critical Part for Industry Safety — the RH928AW is the factory-correct solution that restores operation without system reconfiguration.

Mining & Minerals Processing: Harsh vibration, dust, and temperature cycling accelerate cable wear in mining environments. Keeping genuine Foxboro RH928AW units in maintenance stock prevents extended downtime in ore processing, flotation, and conveyor control systems.

Marine & Offshore Platforms: Offshore DCS installations face corrosive atmospheres and strict safety classifications. Original Factory Sealed components like the RH928AW meet the documentation and traceability requirements demanded by marine classification societies and offshore safety audits.

Data Sheet & Specifications

Quality Assurance & Supply Chain

Every Foxboro RH928AW unit we supply is 100% Original — sourced through verified industrial supply channels and maintained in Factory Sealed condition until the moment of shipment. We do not supply refurbished, remanufactured, or third-party substitute cables under this part number. Each unit undergoes visual inspection and packaging integrity verification before dispatch.

Our 12-Month Comprehensive Warranty covers manufacturing defects, connector failures, and cable insulation integrity from the date of delivery. Should a warranty claim arise, our technical team initiates a replacement process within 48 hours — minimizing your exposure to extended downtime.

For Emergency Repair scenarios, we offer priority dispatch via DHL Express, FedEx International Priority, and UPS Worldwide Express. Global delivery to major industrial hubs typically completes within 2-5 business days. Documentation packages — including commercial invoice, packing list, and certificate of conformance — are provided with every shipment to support your procurement and customs clearance processes.

Buyer’s FAQ — Selection & Sourcing Guide

Q1: How do I verify that the RH928AW I receive is a genuine Foxboro original and not a counterfeit?
A: Authentic Foxboro RH928AW cables carry OEM part number markings on the cable jacket and connector housings. Factory Sealed units arrive in original Foxboro packaging with intact tamper-evident seals. Request a photo of the sealed packaging before shipment, and cross-reference the part number label against Foxboro’s official documentation. We provide full traceability documentation upon request.

Q2: Where can I obtain the official datasheet for the Foxboro RH928AW?
A: The official datasheet is available through Schneider Electric’s Foxboro product documentation portal (Foxboro is now a Schneider Electric brand). Contact our technical team and we will assist you in locating the correct document reference for your system version.

Q3: Is the RH928AW compatible with FCP270 or FCP280E processors?
A: The RH928AW is factory-specified for the FCP280 and standard 200 Series baseplates. Compatibility with FCP270 or FCP280E variants depends on the specific system revision. Provide your system’s hardware revision and software version, and our engineers will confirm compatibility before you place an order.

Q4: Can the RH928AW be used in a redundant FCP280 configuration?
A: Yes. The RH928AW supports redundant Fieldbus communication architectures. In a dual-FCP280 redundant setup, two cables are typically required — one per processor. Confirm your system’s redundancy topology with your DCS documentation before ordering quantities.

Q5: What is the lead time for emergency orders, and do you offer same-day dispatch?
A: In-stock units are dispatched within 24 hours of order confirmation. For critical Emergency Repair situations, contact us directly via email or phone to arrange same-day dispatch with DHL or FedEx priority services. We operate across multiple time zones to support global maintenance teams.

Q6: Does this cable support Maintenance Stock procurement programs or blanket purchase orders?
A: Yes. We support Maintenance Stock agreements for facilities managing Foxboro I/A Series Legacy Components at scale. Volume pricing, reserved inventory allocation, and scheduled delivery programs are available. Contact our sales team to discuss a customized supply arrangement.
