Function:
MBHC-FB-4.HSC*
The FieldConnex
® Compact Power Hub is a modular fieldbus power supply for four segments with lowest power dissipation and smallest foot print. It supports explosion protection e.g. the High-Power Trunk for longest cable run and highest device count. The Power Hub supports optional Advanced Diagnostics for fast fieldbus commissioning and online monitoring.
The motherboard is the wiring interface and is equipped with a DB 25 connector. Manufactured cables with DCS system plugs reduce the number connection points and effort for check-out. Sockets for all modules enable simple installation and replacement without tools. Wire connections can be selected as spring terminals or screw terminals.
This design allows the most compact cabinet layout. Excellent availability and a very long service life are achieved through: passive impedance filter per segment, high-availability fieldbus termination and plug-in connectors with retaining screws. Electronics are optimized for lowest power dissipation and compactness.
