P+F MB-FB-GTR Power Hub Motherboard

Core Performance & Industrial Application

The Pepperl+Fuchs MB-FB-GTR is the FieldConnex Power Hub motherboard for mounting two protocol gateway modules in redundant configuration.

It carries the HD2-GTR series PROFIBUS PA / PROFINET gateways and distributes supply and bus connections between gateway modules and the PA segment.

It supports redundant gateway arrangement for high-availability PROFIBUS PA fieldbus segments in process plants.

It provides VFC alarm output via connectors and a rotary switch for bus addressing and gateway-specific setting.

It allows spring or screw terminal selection and installs on DIN rail in Zone 2 / Class I Div. 2 hazardous areas.

It is widely used as spare replacement in FieldConnex segment coupler and Power Hub cabinets.
