ABB 3BDH000320R0101 LD800HSE Bus Module

Technical Specifications

• Communication Interfaces:
  • 1 x HSE (10/100 Mbps, RJ45)
  • 4 x H1 (31.25 kbps, terminal wiring)
• Power Supply: 24 V DC (±20%, recommended range 19.2–35 V DC)
• Power Consumption: Typically around 4 A (single module), requires a配套 (matching) power module for供电 (power supply)
• Installation: 35 mm DIN rail (conforming to EN 50022), with an IP20 protection rating
• Dimensions: Approximately 47 x 131 x 111 mm (length x height x depth)
• Weight: Around 0.4 kg
• Operating Temperature: 0–50 °C (standard), with extended range options available for certain models
• Redundancy Support: Supports H1 link redundancy and dual-module hot standby, with independent redundant links ensuring fault switching
• Certifications: Standard model for safe areas; optional ATEX/IECEx (Zone 2/Class I, Div.2) versions for hazardous areas

Functional Characteristics

• Multi-Link Access: Features 4 independent H1 master stations (LAS), supporting up to 31 devices per segment with a total bus length of ≤1900 m (when used with compliant cables)
• Transparent Configuration: The upper system can directly access H1 device function blocks without additional mapping configurations
• Efficient Data Interaction: Supports HSE↔H1 and H1↔H1 data redistribution, with up to 4 sub-cycles to reduce network load
• High Reliability: Incorporates hardware redundant links and automatic fault detection, with support for firmware online updates to minimize maintenance costs
• Flexible Expansion: Can be paired with power conditioning modules and mainboard components to achieve single or redundant configurations, adapting to various operational needs
• Integrated Pressure Compensation: Some models include an integrated pressure compensation system that adjusts for both atmospheric pressure and backpressure variations in flare stacks, facilitating compliance with emission regulations

Application Scenarios

• Power Plant DCS Systems: Used for connecting field instruments such as pressure transmitters, temperature sensors, and actuators in boiler, turbine, and auxiliary networks
• Petrochemical/Chemical Plants: Facilitates the networking of Foundation Fieldbus devices in heating furnaces, reactors, and storage tank areas
• Pharmaceutical/Food Industry: Ensures secure communication between field devices and upper-level monitoring systems in clean areas
• Water Treatment/Metallurgy: Enables long-distance fieldbus interconnection and centralized data management
• Process Control: Applied in scenarios requiring precise control of process variables and alarms, such as oxidation processes (e.g., ethylene oxide and propylene oxide production)
• Flare Stack Analysis: Utilized for product purity monitoring, feedstock purification, and inerting or blanketing applications
