The FieldConnex Fieldbus Power Hub is a modular power supply system for Foundation Fieldbus (FF-H1). It provides multiple power supplies for Fieldbus devices via digital data lines.
The Fieldbus Power Hub consists of a motherboard with single or redundant plug-on modules. Available plug-on modules include an isolated power module with 30V and 500mA, designed for high power in the field, especially if used with Segment Protectors or FieldBarriers; an isolated FNICO power module with 17V and 500mA, dedicated for FNICO installation if used in conjunction with segment protectors; and a non-isolated module with Host Spur Protection, designed for use with both Segment Protector and FieldBarrier, while providing additional network segment protection in conjunction with the redundant Host cards. If one card short circuits, the other card and the Fieldbus segment itself will still continue to operate.
