Description

Pepperl+Fuchs MBHC-FB-4R is a four-segment redundant FieldConnex Power Hub motherboard that links FOUNDATION Fieldbus H1 segments to a general-purpose host interface. Integrated segment termination, redundant power-module positions, fault signaling and support for optional diagnostics provide a maintainable physical-layer platform for process automation systems.

The DIN-rail motherboard is rated for 19.2 to 35 V supply operation and up to 12 A, with each fieldbus segment isolated from the others. It is intended for approved Zone 2 or Division 2 installations when assembled with compatible FieldConnex power and diagnostic modules in accordance with the official documentation.

Information

Overview Manuals Product Applications Compatibility Lifecycle & Replacement

Features:

  • Four redundant FOUNDATION Fieldbus H1 segments
  • General-purpose host interface for PLC or process control systems
  • Integrated 100 ohm segment termination
  • DIN-rail mounting for Zone 2 or Division 2 installations
  • Optional basic or advanced physical-layer diagnostics
Pepperl+Fuchs MBHC-FB-4R is a four-segment redundant FieldConnex Power Hub motherboard that supplies isolated fieldbus segments through compatible plug-in power modules.

The motherboard supports a common host interface, fault signaling and optional diagnostics while maintaining segment-to-segment isolation for reliable process automation installations.

MBHC-FB-4R Pepperl+Fuchs: Verify the exact order code, 19.2 to 35 V supply, compatible power modules, termination selection, grounding and hazardous-area requirements before commissioning.
Pepperl+Fuchs MBHC-FB-4R FieldConnex Power Hub Motherboard Manuals, Datasheets, Official Documents, Links Important Notice: Official documents are provided through manufacturer links. Accessories, manuals, cables, calibration data, software, certificates, and other items are not included with this equipment unless listed in the stock item description.
  • Supplying four FOUNDATION Fieldbus H1 segments
  • Connecting fieldbus segments to PLC or process control hosts
  • Providing redundant power to individual fieldbus segments
  • Supporting live field-device work on hazardous-area trunks
  • Adding physical-layer diagnostics to a FieldConnex Power Hub
MBHC-FB-4R is the Power Hub motherboard component, not a standalone fieldbus power system. Application engineering must confirm compatible FieldConnex power and diagnostic modules, the required host interface, segment loading, cable topology and hazardous-area documentation.

MBHC-FB-4R is compatible with the documented FieldConnex Power Hub power modules and optional diagnostic modules for FOUNDATION Fieldbus H1 systems. Confirm the motherboard revision, host-interface connection, terminal option and approved hazardous-area configuration before replacement.

Pepperl+Fuchs lists MBHC-FB-4R as a FieldConnex Power Hub motherboard. Before replacement, record the complete order code and terminal style, isolate power where required, preserve each segment connection and confirm compatibility with the installed power and diagnostic modules. Use the current manufacturer documentation and approvals for any Zone 2 or Division 2 installation. Do not substitute a different motherboard only because the segment count appears similar.

Technical notes

Use only compatible FieldConnex power and diagnostic modules. Verify the 19.2 to 35 V supply, segment wiring, 2.5 mm² conductor limits, grounding, termination selection, enclosure protection and hazardous-area requirements before energizing.
