ABB LD 800HSEEX 3BSE073314R1 Linking Device for Fieldbus Integration

Description

TheLD 800HSE EXis 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 withFF HSE Class 42cstandards 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 external24 VDCpower supply, while theH1links must be powered separately. ItsIP20protection 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.
