Compact power hub released
Pepperl+Fuchs FieldConnex Compact Power Hub. Reportedly designed as a versatile, high performance power supply for larger process automation projects, the FieldConnex Compact Power Hub delivers eight segments of redundant power in less cabinet space than any other comparable power supply on the market. It supports intrinsically safe fieldbus segments according to Entity Ex ic or Ex nL classification, and the High-Power Trunk concept. These power modules are available for 21…23 V / 500 mA or 28…30 V / 500 mA operation.
With a footprint of 150 mm x 268 mm, the FieldConnex Compact Power Hub reportedly requires about one third less space than a comparable standard power module, with no compromise in performance and power. Delivering high performance and power in significantly less space is achieved through the use of especially selected high-performance components and an advanced passive impedance design resulting in minimum heat dissipation.
“The power supply modules that mount on the motherboard are just 12.5 mm. Depending on the module the typical power loss is only 1.3 or 1.6 watts, which promises a long service life with the most efficient control room cabinet-packing density available today. And because the FieldConnex Compact Power Hub is designed with built-in redundancy, two power modules are assigned to each segment. This means that exchanging a failed power module does not require any interruption of the power supply, and will not affect plan operation,” says Brian Traczyk, Product Manager, Pepperl+Fuchs.
The basic design concept of the FieldConnex Compact Power Hub is a compact motherboard that provides all necessary wiring connections and interfaces. All connections are plug-in with retaining screws for long lasting connections, even under continuous vibration. The motherboard is available in different versions to suit varied application needs, including customized interfaces for major DCS systems such as Yokogawa and Invensys. It can hold up to sixteen plug-in power modules to supply redundant power for up to eight FOUNDATION Fieldbus H1 segments. Modules are simply plugged in and safely secured without need for any tools.
The FieldConnex Compact Power Hub supports physical layer diagnostics. Users simply plug Pepperl+Fuchs optionally available Advanced Diagnostic Module (ADM) into the motherboard of the power module. The ADM serves as the link between the physical layer of the fieldbus infrastructure and the Advanced Diagnostic Manager running at the control room, and detects deteriorating signal quality long before it affects plant operation.
