Function: FBTA-228-BPFB-R-8R

The FieldConnex ® Compact Power Hub is a modular fieldbus power supply for eight 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 mounting plate with sockets for redundant FBM-228 host modules. Individual power modules enable simple installation and replacement without tools. For power redundancy with seamless transfer, pairs of modules feed each segment. Dual, redundant bulk power connections are configurable. They permit common or separate supply to FBM and power modules via Invensys or external power source.

This design allows the most compact cabinet layout for large scale projects. Excellent availability and a very long service life is achieved through: passive impedance filter per segment, high-availability fieldbus termination and plug-in connectors with retaining screws and electronics optimized for lowest power dissipation and compactness.
