ProfiHub - PROFIBUS DP Repeater

ProfiHub A5/B5/C5 - 5 Channel DP Spur Repeaters

Introduction ProfiHub A5, B5 and C5 are advanced, flexible and robust network components for PROFIBUS DP installations. They enable long multi-device spur lines and backbone structures with star/tree segments. PROFIBUS DP is a high-speed communication bus that has to comply with strict rules concerning spur lines, because of possible reflections that could lead to communication disturbances. If spur lines or star segments are required, costly investments in repeaters have to be done. Innovative components for such applications are the ProfiHub A5 and B5. These are perfect economic solutions to implement reliable spur lines in high-speed DP networks. They have the functionality of 5 isolated transparent repeaters. This allows network structures with extended spur lines that individually can handle a maximum of 31 devices and a length equal to the main bus.
