The Compact Fieldbus Power Hub serves as a reliable solution for powering devices in hazardous areas, supporting a wide range of PLC and PCS hosts. Its design features 4 segments, allowing for individual modules per segment, with an emphasis on high efficiency and minimal heat dissipation.
The Compact Fieldbus Power Hub is engineered to cater to the demanding requirements of industrial automation within hazardous environments. This product family is specifically designed for use with FOUNDATION Fieldbus H1 and provides a robust power distribution solution that ensures reliable operation in Zone 2/Division 2 areas. Featuring a high-power trunk configuration, it enables live working on devices installed in hazardous locations without compromising safety.
With the option for advanced diagnostics, the power hub enhances system reliability by incorporating passive impedance, which minimizes the risk of failure. Furthermore, the selectable spring or screw terminals allow for flexible installation and ease of maintenance. The hub’s compact form factor and low heat dissipation make it suitable for applications where space and energy efficiency are critical.
