Products Description

ABB advant OCS LD800HSE 3BDH000320R02 in stock

Key Parameters and Features

Core Features & Advantages

• High-Speed Gateway Between HSE and H1: The module's standout feature is its ability to bridge the FF High-Speed Ethernet (HSE) protocol and up to four H1 fieldbus segments . It acts as a Link Master for each H1 link, executing the Link Active Scheduler (LAS) to manage publisher/subscriber communication, enabling transparent integration of FF devices with the host system .

• Redundancy for High Availability: The LD800HSE supports device redundancy, where the corresponding H1 ports of two linking devices are connected to the same H1 link . A separate serial redundancy link ensures reliable failover and monitoring, providing seamless switchover in the event of a failure and maintaining operational continuity in critical processes .

• Versatile Data Communication: The module supports multiple FF communication mechanisms, including Client/Server for accessing device blocks, Publish/Subscribe for cyclic data exchange (with up to 4 sub-cycles per H1 link), and republishing of data between H1 links or from H1 to HSE . This enables flexible data distribution across the control network.

• Robust Industrial Design: The LD800HSE is designed for demanding industrial environments with an IP20 protection rating, CE compliance, and a G3 coating according to ANSI/ISA 71.04 for corrosion protection . An EX version is also available for hazardous area installations (Class I, Division 2, Groups A, B, C, D; ATEX II 3G Ex nA IIC T4 Gc) .

Typical Applications

The LD800HSE is a key component for integrating FOUNDATION Fieldbus devices into control systems across various industries, including:

• Process Industries: Integration of H1 devices (pressure, temperature, flow transmitters, valve positioners) in chemical, petrochemical, and pharmaceutical plants .

• Power Generation: Connecting FF instrumentation in boiler and turbine control systems .

• Oil & Gas: Fieldbus integration in refineries and pipeline monitoring applications .

• Upgrade Projects: Bridging legacy H1 segments (e.g., from Advant Controller 410/450) to newer 800xA systems without replacing existing FF instruments .

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the LD800HSE?
A: It acts as a gateway between up to four FF H1 fieldbus links and a high-speed Ethernet (HSE) subnet, enabling FOUNDATION Fieldbus devices to communicate with an ABB Advant OCS or 800xA control system .

Q2: Is the LD800HSE compatible with AC 800M controllers?
A: Yes. It integrates with System 800xA and AC 800M controllers via the Control Network, typically paired with a CI860 HSE communication interface module in the controller .

Q3: Does the module support redundancy?
A: Yes, it is qualified for redundant use . Two LD800HSE devices can be connected to the same H1 link via a separate serial redundancy link to ensure reliable failover and monitoring .

Q4: How many H1 channels does the LD800HSE provide?
A: The module provides 4 channels of FF H1 fieldbus interface . Each H1 link can support up to 16 FF instruments (per FF standard) .

Q5: What are the key environmental specifications?
A: The module operates from 0°C to +55°C and can be stored from -20°C to +70°C. It is IP20 rated, suitable for DIN rail mounting in control cabinets, and features a G3 coating for corrosion resistance . A hazardous area version (LD800HSE EX) is also available .

Q6: Can the LD800HSE be used with non-ABB controllers?
A: The module is specifically designed for ABB Advant OCS and System 800xA platforms. Its primary integration is with AC 800M controllers via the HSE subnet and CI860 communication interface .

Q7: What does the LD800HSE EX version offer?
A: The EX version is certified for installation in hazardous locations with approvals including UL Class I Division 2, IECEx Ex nA IIC T4 Gc, and ATEX II 3G Ex nA IIC T4 Gc .

Q8: How is the LD800HSE configured?
A: Configuration is performed through ABB engineering tools including Control Builder and Fieldbus Builder FOUNDATION Fieldbus (FBB). The device requires the import of a capabilities file (.cfh) for integration .
