Dual Fieldbus Power Systems

Passes Foundation FF-831 Conformance TestsRedundant Isolated Power for Foundation Fieldbus H1 Segments

Relcom Dual Fieldbus Power Supplies provide isolated power conditioning for two (2) Fieldbus H1 network segments and facilitates the connection of redundant input power supplies.

An alarm circuit provides warning in case of a power conditioning module or input power supply failure.

The system is designed so that power for several Fieldbus segments can be provided from a single cabinet with minimal wiring.

One Fieldbus segment terminator is included for each segment in the FPS-DT model. Where built-in terminators are not desired, use the FPS-D model.
