Dispozitiv retea Profihub A5 - 5 Channel DP Spur Repeater

Introduction

ProfiHub A5 is an advanced, flexible and robust network component for PROFIBUS DP installations. It enables long multi-device spur lines and backbone structures with star/tree segments in IP 65 applications.

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.

The ProfiHub A5 is a perfect economic solution to implement reliable spur lines in high-speed DP networks. It has the functionality of 5 galvanic 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.
