Description
Pepperl+Fuchs MBHC-FB-4R is the motherboard and host-side wiring interface for a compact FieldConnex Power Hub serving four redundant FOUNDATION Fieldbus H1 segments. Its plug-in architecture centralizes segment power, host connections, alarm wiring, and diagnostic-bus connections in one cabinet assembly.

The board is intended for process automation cabinets that require redundant fieldbus power and flexible integration with PLC or PCS host systems. It supports high-power trunk arrangements, passive segment impedance, and optional physical-layer diagnostics for commissioning and online maintenance work.

For replacement or new installation, confirm the host interface, terminal arrangement, power-module selection, diagnostic option, and hazardous-area concept before ordering. DIN-rail mounting, cable preparation, grounding, and energized-circuit work must follow the applicable Pepperl+Fuchs instructions and site safety procedures.
