Bus Cables

Profibus L2 Direct Burial

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 above

mentioned type is suitable for underground installation and is equipped with a special PVC/PE jacket.
