Product Introduction & Supply Chain Strategy
The ABB LD800HSEEX 3BSE073314R1 is a FOUNDATION Fieldbus Linking Device that connects four FF H1 segments to a High-Speed Ethernet (HSE) network. It enables engineering stations and controllers to configure field instruments, exchange process data, distribute alarms, and manage diagnostics across FOUNDATION Fieldbus installations.
Purchasing this unit as New Surplus provides genuine OEM hardware while eliminating the uncertainty associated with refurbished communication equipment. Since these specialized gateways are essential for maintaining fieldbus communication, maintaining buffer stock, reducing lead time variability, implementing vendor consolidation, and planning last-time-buy purchases can significantly reduce Total Cost of Ownership (TCO) and prevent extended production outages.
Installation & Configuration Guide
Stage 1 – Pre-Installation (Prep & Safety)
- Perform Lock-Out/Tag-Out (LOTO).
- Disconnect the 24 VDC power supply.
- Wear a grounded ESD wrist strap.
- Record:
- IP configuration
- H1 segment assignments
- Node configuration
- Photograph all Ethernet and H1 terminal wiring.
Stage 2 – Removal
- Verify complete power isolation.
- Disconnect Ethernet and H1 cables.
- Remove the DIN rail retaining clip.
- Carefully remove the module without stressing the terminals.
- Inspect all wiring and connectors for corrosion or damage.
Stage 3 – Installation (Clone & Seat)
- Confirm the replacement model is LD800HSEEX 3BSE073314R1.
- Mount the unit securely on the DIN rail.
- Reconnect the 24 VDC supply.
- Restore all H1 and Ethernet connections.
- Verify proper grounding and cable shielding.
Stage 4 – Power-On & Testing
- Apply 24 VDC power.
- Verify normal status LEDs.
- Confirm communication with all four H1 segments.
- Test HSE connectivity from the engineering workstation.
- Verify field device discovery, diagnostics, and alarm reporting before returning the system to operation.

Firmware/Software Versions & Upgrade Notes
- Verify compatibility with the installed ABB 800xA or AC 800M FOUNDATION Fieldbus environment.
- Back up the device configuration before replacement.
- Confirm firmware compatibility with connected H1 devices.
- Do not combine firmware upgrades with hardware replacement during scheduled production unless required.
- ABB specifies that 3BSE073314R1 is not suitable as a replacement for article number 3BDH000320R0101 in a redundant device pair, so verify existing hardware before ordering.
- After commissioning, verify redundant communication (if applicable), device discovery, and HSE network diagnostics.
Frequently Asked Questions (FAQ)
Q1. Is this unit genuinely new?
Yes. This product is supplied as New Original / New Surplus. It is not used, not repaired, and not refurbished. Every device undergoes quality verification before shipment.
Q2. Why is New Surplus less expensive than purchasing directly from ABB?
New Surplus inventory originates from excess project inventory and authorized surplus channels. It provides genuine OEM equipment while avoiding the reliability concerns associated with refurbished communication hardware.
Q3. What does the LD800HSEEX do?
It serves as a gateway between four FOUNDATION Fieldbus H1 segments and a High-Speed Ethernet (HSE) network. It supports device configuration, process data exchange, alarm distribution, diagnostics, and system management for FOUNDATION Fieldbus installations.
Q4. Can this module be installed in hazardous areas?
Yes. The is certified for ATEX and IECEx Zone 2 installations when installed according to ABB guidelines.
Q5. Can I replace the device while the system remains energized?
No. Power should be isolated before replacing the linking device unless your system architecture and maintenance procedures explicitly support online replacement.
Q6. What quality inspections are completed before shipment?
Each New Surplus unit undergoes:
- OEM part number verification
- Serial number traceability
- Visual inspection
- Communication port inspection
- Power terminal inspection
- ESD-safe packaging
- Final QC approval documentation
Q7. What spare parts strategy is recommended?
For critical FOUNDATION Fieldbus networks:
- Maintain 1–2 units as on-site buffer stock.
- Use vendor consolidation to improve procurement efficiency.
- Implement cross-site inventory sharing where multiple plants operate ABB 800xA systems.
- Review lifecycle status regularly and execute a last-time-buy strategy before availability declines, reducing lead time variability and lowering long-term Total Cost of Ownership (TCO).
