MTL and Relcom fieldbus power supplies provide reliable power for fieldbus networks in safe and hazardous areas. All types incorporate isolation between bulk power supply and the fieldbus wiring, to prevent segment failure in the event of multiple ground faults.

Non-redundant, general purpose applications
The compact, DIN-rail mounted MTL5995 isolated power supply has become the established industry standard for general purpose fieldbus applications. The FPS-D/DT dual power supply powers two independent fieldbus segments from a single module carrier, and provides easy interconnection of bulk power supplies in multi-segment installations.

Redundant, general purpose applications
For applications requiring high system availability, the established FPS-Series Redundant Power System includes redundant, isolated power conditioning modules and comprehensive alarm monitoring. The F600A, F650A and F690A variants are available for integration into fieldbus control systems. Large-scale fieldbus installations will benefit from the new F800 Series Redundant Power System, which delivers the highest levels of reliability in a compact, high-density format.

Hazardous area applications
FISCO (Fieldbus Intrinsically Safe COncept) power supplies provide power and signal repeater functions for an intrinsically safe bus in Zone 1 and Division 1 hazardous areas, using the same simple network design rules as general purpose fieldbus

For applications in Zone 2 and Division 2 hazardous areas, MTL's unique FNICO (Fieldbus Non-Incendive COncept) power supplies deliver all the benefits of FISCO, together with a wider choice of compatible field instruments and more instruments per fieldbus trunk.
