Bus Cables
Profibus L2 Indoor
Application:
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 fieldbus systems are used. The types
mentioned here are suitable for indoor laying and are equipped with a special PVC jacket.
