FOUNDATION Fieldbus Linking Device LD 800HSE

The LD 800HSE linking device serves as a gateway between the field devices on the H1 links and the HSE subnet.

LD 800HSE enables the access to field devices connected to the FOUNDATION Fieldbus (FF) from supervisory and control systems as well as management consoles. The device is qualified for redundant use, where the corresponding H1-ports of two Linking Devices are connected to one H1 link. A separate redundancy link between primary and secondary Linking Devices ensures reliable failover and monitoring of redundancy.

Two different versions are available, one for safe areas and one for hazardous areas.
