ABB LD 800HSE (3BDH000320R0101) – FOUNDATION Fieldbus HSE Linking Device for H1 Segments

From my experience, the ABB LD 800HSE is the piece that quietly makes FOUNDATION Fieldbus plants run smoother. It bridges your high‑speed Ethernet (HSE) control network to multiple FF H1 field segments, so controllers and asset tools in 800xA or similar DCS environments can talk to instruments without drama. You might notice that commissioning tends to be faster and segment diagnostics more transparent compared with older gateways. The order code 3BDH000320R0101 points to the ABB hardware variant commonly deployed in process plants where uptime really matters.

Key Features

• HSE–H1 Linking – Connects high‑speed Ethernet (HSE) networks to multiple FOUNDATION Fieldbus H1 segments, enabling controller and asset tool access to field devices.
• Designed for ABB 800xA ecosystems – Integrates cleanly with ABB engineering/asset suites in many cases, streamlining device management and diagnostics.
• Segment Capacity – Supports multiple H1 channels (typically up to 4), reducing gateway count and cabinet space.
• Deterministic Scheduling – Handles FF function block scheduling and publisher/subscriber traffic for stable process loops.
• Built‑in Diagnostics – Segment status, device health and traffic counters help technicians find wiring or power issues faster.
• Industrial Ethernet – 10/100Base‑TX connection to the control network; easy to pair with redundant topologies at the system level.
• 24 VDC Cabinet Power – Runs from standard 24 VDC plant supplies; typical low power draw.

Technical Specifications

Application Fields

Typically used in process industries that standardized on FOUNDATION Fieldbus at the device layer while keeping Ethernet at the control layer:

• Oil & Gas and Petrochemical – integrating smart transmitters, valve positioners and skid packages into ABB 800xA.
• Power Generation – boiler/BTG loops with FF‑based instrumentation tied to plant DCS over HSE.
• Water & Wastewater – distributed FF H1 segments across galleries with centralized diagnostics.
• Pharma & Specialty Chemicals – consistent device parameter management and batch‑oriented orchestration.

A maintenance lead at a chemical plant told us they replaced three aging gateways with two LD 800HSE units and cut troubleshooting time in half because segment errors were just obvious on the diagnostic pages.

Advantages & Value

• Reliability – Robust ABB hardware designed for continuous operation; fewer moving parts than PC‑based gateways.
• Compatibility – Works neatly with ABB 800xA control/asset frameworks; supports standard FF H1/HSE behavior for multi‑vendor devices.
• Cost Savings – Higher segment density (in many cases up to 4 H1) reduces cabinet space, power supplies, and cabling.
• Diagnostics = Less Downtime – Quicker isolation of bad drops, missing terminators, or overloaded segments.
• Lifecycle Support – Firmware updates and documentation backed by a mature installed base.

Installation & Maintenance

• Cabinet & Mounting – Install on DIN rail in an IP20 (or better) control cabinet; keep adequate ventilation and avoid heat sources.
• Power – Supply regulated 24 VDC with proper grounding; dedicate circuit protection for each device.
• Fieldbus Wiring – Use FF‑certified shielded twisted pair for H1; power conditioners and segment terminators are required; maintain trunk/spur length limits per FOUNDATION Fieldbus guidelines.
• Network – Connect HSE port(s) to your control network (10/100Base‑TX). Redundancy can be achieved at the switch level or system architecture.
• Safety – For hazardous areas, pair with suitable FF power conditioners/isolators rated for IS where applicable.
• Routine Care – Periodically back up configuration, check segment loads and alarms, clean ventilation openings, and apply vetted firmware updates during planned outages.

Quality & Certifications

• CE compliant; RoHS
• UL/cUL listing for industrial control equipment (typical)
• FOUNDATION Fieldbus compliant (H1/HSE); IEC 61158
• Manufacturer warranty: 12 months
