Product Introduction (No Fluff)

The ABB LD 810HSE EX (3BSE091722R1) is a Foundation Fieldbus HSE-to-H1 linking device designed for process automation systems requiring hazardous-area certification. It bridges a high-speed Ethernet HSE backbone with up to four isolated FF-H1 fieldbus segments, enabling seamless integration of field instruments such as transmitters, valve positioners, and analyzers into ABB 800xA or Advant OCS control systems.

Each H1 channel operates independently at 31.25 kbps and supports up to 32 field devices per segment. The device provides full Foundation Fieldbus device management, including function block access, alarm/event distribution, and diagnostic data collection via the HSE network. Redundant linking pairs can be configured for fault-tolerant operation with seamless switchover.

The “EX” designation indicates ATEX/IECEx Zone 2 certification (Ex nA IIC T4 Gc), making it suitable for installation in hazardous areas such as oil & gas, petrochemical, and power generation facilities. It is commonly deployed as a successor to the older LD 800 series linking devices.

 

QA & Testing SOP (Dynamic & Transparent)

 

1. Order code verification: Confirm the device is labeled LD 810HSE EX with order code 3BSE091722R1.
2. Incoming visual inspection: Check housing integrity, RJ45 port, H1 terminal blocks, DIN-rail clips, and nameplate for damage or corrosion.
3. Power-up test: Apply 24 V DC (18–32 V range) and verify normal LED indicators without fault status.
4. HSE connectivity test: Connect to 10/100 Mbps Ethernet and verify IP connectivity and web interface access.
5. H1 channel verification: Confirm each of the four H1 channels reports normal segment status and can discover connected field devices.
6. Redundancy test (if applicable): In redundant pairs, verify primary/secondary switchover behavior.
7. Firmware and configuration check: Verify firmware version and configuration backup compatibility with the target system.
8. ESD-safe handling and packing: Store and ship in anti-static packaging; protect RJ45 and terminal connectors.

 

Installation Pitfalls & Guide (Engineer to Engineer)

❗ Zone 2 certification applies. The LD 810HSE EX is certified for Zone 2 hazardous areas. Verify that the installation environment matches the ATEX/IECEx rating and that all wiring complies with intrinsic safety or non-incendive requirements as applicable.

❗ Do not mix with non-EX variants. The LD 810HSE EX (3BSE091722R1) is not interchangeable with non-hazardous-area linking devices without reviewing system design and certification requirements.

❗ H1 segment loading matters. Each H1 channel supports up to 32 devices. Exceeding device count or cable length limits can cause communication faults. Verify segment design before commissioning.

❗ Redundancy requires paired configuration. If replacing one unit in a redundant pair, confirm firmware compatibility and re-synchronize the pair after installation.

❗ Web interface access. Configuration and diagnostics are performed via HTTP/HTTPS. Ensure network access policies allow management traffic to the device IP address.

Replacement steps:

1. Pre-install: Document existing IP addresses, H1 segment assignments, redundancy settings, and firmware version. Back up configuration if the failed unit is still accessible.
2. Removal: Disconnect 24 V DC supply, HSE Ethernet cable, and H1 fieldbus wiring. Remove from DIN rail.
3. Install: Mount the new LD 810HSE EX on DIN rail. Reconnect HSE Ethernet, H1 wiring, and 24 V DC supply.
4. Configuration: Assign the correct IP address, restore configuration, and verify H1 segment status.
5. Commissioning: Confirm device discovery on each H1 segment, verify process data flow to the 800xA or Advant OCS system, and test redundancy switchover if applicable.
