Overview

The LD 800HSE EX is a robust and compact linking device that bridges four FOUNDATION Fieldbus H1 links (31.25 kbit/s) with a single HSE Ethernet interface (10BASE-T/100BASE-TX). This enables seamless integration of field devices into plant-wide control and monitoring systems. The device complies with FF HSE Class 42c standards and supports redundant configurations, making it ideal for mission-critical process automation environments.

Moreover, the LD 800HSE EX is DIN rail mountable, simplifying installation in control cabinets. It requires an external 24 VDC power supply, while the H1 links must be powered separately. Its IP20 protection rating and compact footprint make it suitable for both new installations and retrofit projects.

For example, engineers in chemical plants and refineries use the LD 800HSE EX to consolidate fieldbus segments and improve diagnostic visibility across distributed assets.

Technical Data

Typical Applications

• Process Automation: Connects field devices in chemical, pharmaceutical, and oil & gas plants to control systems.

• Power Generation: Integrates turbine and boiler instrumentation into centralized monitoring platforms.

• Industrial Networking: Bridges low-speed fieldbus segments with high-speed Ethernet backbones.

• Hazardous Area Installations: Certified for Zone 2 environments, suitable for explosive atmospheres.

• OEM Control Panels: Embedded in custom automation solutions requiring multi-segment fieldbus integration.

For instance, facilities with multiple FOUNDATION Fieldbus segments benefit from the LD 800HSE EX’s ability to consolidate data and enhance system diagnostics.
