ABB LD800HSE-3BDH000320R02 – FOUNDATION Fieldbus HSE Linking Device for seamless 800xA integration

The ABB LD800HSE (rev R02, order code 3BDH000320R02) is a high-speed Ethernet linking device designed to bridge FOUNDATION Fieldbus H1 segments into an HSE backbone and directly into System 800xA. From my experience, it’s typically used where you want deterministic H1 device data brought into the control network without adding unnecessary complexity in the cabinet. You might notice that the unit is happiest in a standard 24 VDC DIN-rail installation, where it provides reliable H1/HSE gateway services and works smoothly with ABB’s fieldbus management tools.

Key Features

• FOUNDATION Fieldbus H1 to HSE gateway – Aggregates H1 device data and exposes it on High-Speed Ethernet for 800xA.
• Optimized for System 800xA – Typically recognized quickly in ABB engineering tools, helping reduce commissioning time.
• Deterministic data handling – Designed for stable H1 scheduling and reliable cyclic data, even across multiple segments.
• Industrial Ethernet (10/100Base‑TX) – Standard RJ45 connection simplifies control network layout and switch selection.
• DIN‑rail installation – Compact, cabinet-friendly footprint with straightforward 24 VDC power wiring.
• Segment scalability – In many cases supports multiple H1 segments (via appropriate power hubs/conditioners), making expansions easier.
• Maintainable firmware – Firmware updates and diagnostics typically handled through standard ABB utilities.

Technical Specifications

Notes: Number of H1 segments supported depends on the specific configuration and external power hubs. The device typically does not supply H1 power by itself.

Application Fields

• Oil & Gas and Petrochemical – Integrating FF transmitters, valves, and analyzers into 800xA over HSE.
• Chemical & Specialty Chemical – Reliable segment scheduling for regulatory loops.
• Pharmaceuticals – Batch environments where device diagnostics on H1 are essential.
• Power Generation & Utilities – Turbine balance-of-plant instruments on FF H1 mapped to the control network.
• Pulp & Paper – Segment-heavy areas with frequent device adds/changes.

Advantages & Value

• Reliability – Solid H1/HSE handling minimizes dropouts; in many cases runs for years with only scheduled maintenance.
• Compatibility – Works with 800xA fieldbus toolsets and common FF devices from major vendors.
• Cost Control – Consolidates multiple H1 segments into one HSE path, which typically reduces the number of host interface cards.
• Serviceability – Straightforward firmware updates and diagnostics help shorten downtime.
• Future‑ready topology – Ethernet backbone makes later expansions more predictable.

Installation & Maintenance

• Cabinet & Mounting – Install on DIN‑rail in a ventilated enclosure (IP20 or better inside). Keep ambient within 0–55 °C.
• Power & Grounding – Feed with regulated 24 VDC and bond protective earth. Keep clean, isolated instrument power where possible.
• H1 Segment Design – Use certified H1 power conditioners/hubs and proper terminators. Respect spur lengths and device counts per segment.
• Ethernet Practices – Connect to an industrial managed switch; enable VLAN/QoS if your control network policy requires it.
• Maintenance – Schedule periodic backups of configuration, review device diagnostics, clean dust from vents, and keep firmware at the recommended revision.
• Safety – De‑energize segments before re-terminating. For hazardous areas, place this unit in a safe area and use appropriate field barriers on the H1 side.

Field feedback: a maintenance lead in a refinery told us the LD800HSE “just sits there and runs”; the only time they touch it is during planned firmware rollups or when adding a new H1 segment.

Quality & Certifications

• CE compliant; RoHS conform
• UL/cUL for industrial control equipment (typical for this class of device)
• Manufacturer warranty is usually 12 months; our supply warranty: 365 days
• Conforms to FOUNDATION Fieldbus H1/HSE standards

Related Components (often used together)

• FOUNDATION Fieldbus power hubs/conditioners – e.g., MTL 918x/919x or Pepperl+Fuchs FieldConnex hubs to energize H1 segments and provide short‑circuit protection.
• DIN‑rail 24 VDC power supply – 30–60 W class, redundant if required for high availability.
• Industrial managed Ethernet switch – 10/100/1000Base‑T with IGMP Snooping and QoS for control traffic.
• Surge protection and earthing kits – To improve segment robustness in electrically noisy areas.

One thing I appreciate is how the LD800HSE simplifies brownfield upgrades: you can keep your proven FF H1 field layer intact while moving the host side to a cleaner Ethernet topology. If your application has a specific segment count or redundancy scheme in mind, share the details and we’ll recommend a tested configuration that typically avoids surprises during FAT/SAT.
