Fieldbus hub provides multiple power supplies


General DPN

DPN WEB EXCLUSIVE: Pepperl+Fuchs introduces the FieldConnex Fieldbus Power Hub (FPH), the latest component-level solution to its FieldConnex Fieldbus Installation System. The modular power supply system for Foundation Fieldbus (FF-H1) 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. Multiple plug-on
modules are available, including: isolated power module with 30 V and 500 mA ñ
designed for high power in the field, especially if used with Segment
Protectors or Field Barriers; isolated FNICO power module with 17 V and 500 mA ñ dedicated for FNICO installation if used in conjunction with segment
protectors; and, non-isolated module with Host Spur Protection ñ designed for
use with both Segment Protector and Field Barrier, 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.
