ABB LD 810 | System 800xA S900 Spare

Description

• Model & Brand: ABB LD 810, identified in ABB System 800xA documentation as the LD 810 HSE EX Linking Device.
• System: ABB System 800xA / S900 Remote I/O architecture.
• Function: Linking device providing four H1 links and one HSE connector; the module requires an external 24 VDC power supply, while the H1 links require separate power.
• Mounting: DIN-rail mounting.
• Article Number: 3BSE091722R1 for the LD 810 HSE EX version documented by ABB.
• Physical Dimensions: Exact W × H × D dimensions should be confirmed from the applicable ABB hardware manual before cabinet-layout approval. Do not substitute dimensions from another LD-series linking device.
• Estimated Shipping Weight: Allow approximately 1–2 kg packaged for preliminary freight planning; obtain the actual packed weight from the shipment record for a customs declaration.
• What’s in the Box: Linking-device module and manufacturer packaging. Do not assume DIN-rail accessories, redundancy cable, external 24 VDC power supply, or H1 power accessories are included unless specifically listed.

Product Introduction

Hazardous-area compatibility is central to the LD 810 HSE EX configuration. This ABB linking device is designed for the S900 Remote I/O architecture and provides the physical bridge between the H1 fieldbus level and the HSE network. Its DIN-rail form factor is intended for cabinet installation, while the external 24 VDC supply must be accounted for separately during cabinet engineering.

The exact suffix matters here. ABB’s catalog identifies LD 810 HSE EX, article 3BSE091722R1, and explicitly states that it cannot be used as a one-for-one replacement for one LD 800 device in a redundant pair. If an existing redundant pair is being migrated, both devices must be replaced with LD 810 HSE EX units (a useful distinction during spare-parts auditing).

Core Technical Specifications

ABB LD 810

ABB’s System 800xA catalog specifically describes the LD 810 HSE EX as a DIN-rail-mounted module with four H1 links and one HSE connector.

? Global Compliance & Industry Certifications

For the HSE EX version, certification verification is particularly important because the product is intended for installations where hazardous-area requirements may apply.

Expected regulatory documentation should be checked for:

• CE Mark — applicable European conformity marking.
• ATEX — particularly important when the equipment is installed in an ATEX-classified hazardous area.
• IECEx — verify whether the exact LD 810 HSE EX hardware revision carries the required IECEx certificate.
• UL/cUL — verify against the exact ABB ordering code and intended installation.
• Marine approvals — such as DNV, ABS, or LR should not be assumed without a certificate for the exact configuration.

ATEX/IECEx documentation matters because the certification defines the permitted hazardous environment, equipment protection concept, and installation conditions. A standard LD-series module should never be treated as equivalent to an HSE EX model simply because the enclosure and connectors appear similar.

Verify specific lot certifications with OEM.

? Long-Term Storage & Asset Preservation Guide

1. Keep the LD 810 in its original ESD-protective packaging. The HSE network connector and H1 interface circuitry should remain protected from dust, moisture, and electrostatic discharge until installation.
2. Protect the DIN-rail locking mechanism and connectors. Do not store the module loose in a mixed hardware bin. Mechanical damage to the retaining mechanism or connector housing can prevent correct seating even when the electronics remain functional.
3. Control humidity and temperature cycling. For long-term warehouse storage, maintain a dry, temperature-stable environment and target below 60% RH where practical. Condensation is a greater concern than the absolute storage temperature for a cabinet-mounted communications module.

For an EX-rated spare, preserve the nameplate and certification label. Do not allow warehouse labels, paint, adhesive, or packaging abrasion to obscure the certification markings.

Physical Installation Prerequisites

• Mount the LD 810 HSE EX on the specified DIN rail with the locking mechanism fully engaged.
• Provide cabinet clearance around the module for connector access, cable routing, inspection, and thermal dissipation. Exact clearance should follow the applicable ABB installation manual.
• Provide the required external 24 VDC supply. The module does not eliminate the need for a properly engineered cabinet power source.
• Supply the H1 links separately as required by the ABB architecture.
• Maintain proper cabinet protective-earth bonding and follow ABB’s EMC grounding practices.
• Verify the HSE network connection and H1 fieldbus wiring before commissioning.
• For redundant LD 800 installations being upgraded, replace the complete redundant pair with the specified LD 810 HSE EX configuration rather than mixing generations.

Buyer’s FAQ

Q: Which HS tariff code should be used for LD 810?
There is no single universal HS code that should be declared solely from the model number. The correct classification depends on the customs jurisdiction and the product’s principal function as a communications/linking device. Have the importing broker validate the applicable national tariff subheading before filing the commercial invoice.

Q: Does the Country of Origin affect this shipment?
Yes. COO can affect preferential tariff eligibility, import controls, and documentary requirements. Use the origin shown on the physical product documentation or an appropriate supplier/OEM origin declaration rather than copying COO from an unrelated LD-series listing.

Q: Should shipping insurance be purchased?
For international shipment, yes—particularly for an EX-certified automation module. Use ESD protection, rigid outer packaging, adequate cushioning, and insurance based on the declared replacement value. Preserve the certification label during packing.

Q: Does LD 810 include the latest firmware pre-loaded?
Do not assume that a newly supplied or factory-sealed unit contains the latest site-approved firmware. Firmware compatibility should be checked against the installed System 800xA/S900 environment and the exact hardware revision before commissioning. The physical article number alone does not establish the firmware version.
