PROFIBUS (PROCESS FIELD BUS) which is anchored in the international standards IEC 61158 and IEC 61784 is an open, digital communication system with a wide range of applications, particularly in the fields of factory and process automation. The CNT-PROFI connector is used to connect a PROFIBUS node to the PROFIBUS line featuring quick-connect technology, making the stripping of bus conductors superfluous. The connector is quick to install, and has a plastic housing and integrated terminating resistors. Anyway the CNT-PROFI could link a PROFIBUS device to a PROFIBUS line easily and fast.
