Profibus L2 UL FT4


Applications :

  • This system cable is used to interconnect L2-BUS components.
    This cable is an economical solution for the cell and field area. For the information exchange between different automation systems as well as for communication with the connected decentralized field units, serial field bus systems are used. The type described here is suitable for the installation in areas where the FT4 standard (special fire standard “vertical tray”) according to UL/CSA applies. For this purpose the line was equipped with a special outer PVC jacket.
