Profibus L2-Torsion + Festoon

Profibus L2-Torsion + Festoon


The series TORSION and FESTOON are used to interconnect Profibus BUS components. This BUS system is a very

economical solution for the 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

lines described here are designed torsionable or hanging movable construction. Areas such as robot applications

and/or garland suspension are easily realized.
