The FieldConnex Compact Power Hub is designed as a versatile, high performance power supply for larger process automation projects. The unit delivers eight segments of redundant power in less cabinet space. It supports intrinsically safe fieldbus segments according to Entity Ex ic or Ex nL classification, as well as the High-Power Trunk concept. These power modules are available for 21-33 V/500 mA or 28-30 V/500 mA operation. A compact motherboard provides all necessary wiring connections and interfaces. All connections are plug-in with retaining screws for long lasting connections, even under continuous vibration.
