Compact Fieldbus Power Hub, Motherboard, Redundant Host Terminals
Opis
8 segments, redundant, individual modules per segment, Supports all PLC and PCS hosts, redundant terminals, High-power trunk: Live work on devices in any hazardous area, Best quality, smallest size and lowest heat dissipation, For FOUNDATION Fieldbus H1 and PROFIBUS PApa. 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 with redundant terminals for all DCS and PLC host systems on the left side of the motherboard. The version with type code extension ".R" has redundant terminals for host connections on the right side for symmetrical cabinet layout. Sockets for all modules enable simple installation and replacement without tools. For power redundancy with seamless transfer, pairs of modules feed each segment. 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 plugs with retaining screws. Electronics are optimized for lowest power dissipation and compactness.
