Product overview:
- FOUNDATION Fieldbus gateway between HSE Ethernet and four H1 links
- Four independent H1 Link Active Schedulers with data republishing
- Zone 2 / Class I Division 2 hazardous-area version with redundancy support
is an ABB FOUNDATION Fieldbus linking device that connects one High Speed Ethernet subnet to as many as four independently scheduled H1 links. ABB identifies the hazardous-area hardware as article number 3BSE073314R1.
The device provides one autosensing 10/100 Mbit/s Ethernet channel, four galvanically isolated 31.25 kbit/s H1 interfaces and a serial redundancy link. It requires an external 24 V DC supply, while each H1 segment must be powered through suitable fieldbus power conditioning.
LD800HSE EX is intended for supported Zone 2 or Class I Division 2 installations subject to the complete approval conditions. Confirm firmware, HSE addressing, H1 segment design, redundancy partner, power conditioners and certificate markings before commissioning or replacement.
