Description

ABB LD800HSEEX 3BSE073314R1

Technical Specifications:

  • Safety Certification: ATEX / IECEx certified for Zone 1/Zone 2 or Division 1/Division 2.
  • I/O Type: Analog and/or discrete inputs/outputs.
  • Intrinsic Safety: Energy-limited circuits preventing ignition.
  • Part Number: 3BSE073314R1.

Functional Features:

  • Safe Area Interface: Allows connection of IS field devices from a safe area control cabinet.
  • Fault Tolerance: Designed to fail safely without generating sparks or excessive heat.
  • Diagnostics: Continuous monitoring of loop integrity and field device health.
  • Redundancy: Supports redundant field wiring for critical safety applications.

Application Scenarios:

  • Oil and gas offshore platforms and refineries.
  • Chemical processing and pharmaceutical manufacturing.
  • Grain elevators and coal handling facilities.

Performance Parameters:

  • Loop Power: Intrinsically safe loop power supply for 2-wire transmitters.
  • Accuracy: High-precision measurement despite safety barriers.
  • Response Time: Fast enough for process control and safety interlocks.

Material Composition & Structural Characteristics:

  • Enclosure: Flameproof or increased safety enclosure with certified cable glands.
  • PCB: Components rated for intrinsic safety with current-limiting resistors and fuses.
  • Labeling: Permanent safety markings and certification labels.

Working Principle:
The module uses intrinsic safety barriers (Zener diodes, resistors, fuses) to limit the electrical energy flowing to the hazardous area. Even under fault conditions, the energy is insufficient to ignite the surrounding atmosphere. The module safely conditions and transmits the field signals to the control system.

Installation Requirements:

  • Certification Compliance: Strictly follow the approved hazardous area drawing and installation manual.
  • Cable Glands: Use only certified cable glands and maintain IP rating.
  • Grounding: Implement the required intrinsic safety earth ground system.

Usage Precautions:

  • No Live Work: Never open the enclosure or disconnect field wiring in a hazardous area while energized.
  • Component Replacement: Only use certified replacement parts to maintain safety integrity.
  • Inspection: Regularly inspect seals, glands, and enclosures for damage or degradation.
