Redundant FPS200 TRUNKGUARD modules can be “hot swapped” without adversely affecting fieldbus communications December 1, 2006 - NORTH HILLS, CA - MooreHawke, a division of Moore Industries-International, Inc., introduces the FPS200 TRUNKGUARD Fieldbus Power Conditioner. The FPS200 provides conditioned power for FOUNDATION Fieldbus H1 networks in general purpose and non-incendive applications. It is available in both simplex (non-redundant) and duplex (redundant) models.The simplex configuration allows up to eight FPS200 power conditioner modules to be installed on a single DIN-rail carrier to provide power to up to eight individual H1 fieldbus segments.
Each plug-in module provides 350mA at 26V of isolated, conditioned power, fully compliant with the FF831-1 fieldbus specification. The FPS200 is FOUNDATION fieldbus registered.The duplex configuration provides redundant, load-sharing, hot-swappable power conditioners. During normal operation, two modules share the supply load to one H1 segment. If one module fails, the other module seamlessly picks up the entire load.
Individual power conditioners can be hot swapped—that is, added to or removed from the DIN-rail carrier without powering down the system—without affecting fieldbus communications. A FPS200 TRUNKGUARD Fieldbus Duplex Power Carrier with eight power conditioners can support four H1 segments.On-board segment diagnostics include an LED that indicates segment short circuit, low voltage output to the segment, and low supply voltage to the carrier board. Also included is a volt free contact closure output that can be wired the host system for alarm notification. Optional surge protection, rated at 20kA, protects the segment from power surges.
