Hampton, NH... The next generation in fieldbus power systems is here – the F800 series from MTL-Relcom. A high-density, redundant fieldbus power supply, the F800 is designed to achieve low per-segment cost and high packing density in large fieldbus installations. The F800 uses 8-channel power supply modules in a redundant format on a passive base – the “Naked Carrier” concept. With up to 50% space saving over existing fieldbus power supplies, the highest levels of system availability are achieved by eliminating all single points of failure. Savings in hardware overhead allow the F800 to provide redundant fieldbus power for the same cost as previous generation “simplex systems” – so redundancy essentially comes for free. A key feature of the F800 Series is a network monitoring option. This allows the F800 to continuously monitor the health of installed fieldbus segments. This capability can speed-up the fault finding of errant networks, providing valuable information on the health of the physical layer. Parameters measured include segment voltages, signal levels of all devices and noise in three bands. Fieldbus-to-shield short circuits and improperly terminated wiring are also indicated. The F800 Series power supplies are available in a wide variety of formats for easy integration into leading fieldbus control systems. The F800 can be integrated with Yokagawa Centum CS3000 and Honeywell Experion/PKS architectures using standard system cables. Conventional cabling techniques can be used for Emerson Delta V and other carrier-based installations.
