The PROFIBUS couplers and PROFIBUS repeaters have been particularly dimensioned for the industrial requirements of hazardous areas of zone 1.

PROFIBUS couplers and PROFIBUS repeaters are used for the separation or generation of new segments, converting the RS485 typical line structure into an open and flexible tree structure. Downstream stations can be coupled to and decoupled from the superior bus system in a nonreactive and break/short-circuit tolerant manner, even during running bus operation.

The devices facilitate a duplication of the signal to realize a redundant connection to a master.

The devices are available as PROFIBUS-DP and as PROFIBUS-IS (intrinsically safe).

Module tasks:

• Separation of bus segments or generation of new segments
• Creation of complex networks in line, star and tree structures
• PROFIBUS-conforming regeneration of the bus signals in amplitude and time
• Increase of station number
• Segment cascading for range increase
• Provision of intrinsically safe bus segments for Ex i version in acc. with RS485 IS.
