Function
The Segment Coupler 1 (SK1) is an all-in-one gateway and fieldbus power supply for connecting PROFIBUS PA to PROFIBUS DP transparently. The Segment Coupler powers a single PROFIBUS PA segment adapting current and voltage.
Power output is designed for long cable lengths and device counts suiting the needs of most fieldbus applications. Device couplers provide explosion protection for live work at the spur where needed.
Communication is transparent between DP and PA. The gateway of the Segment Coupler makes each PA device appear as if it was connected to DP: This relates to addressing, cyclic/acyclic data exchange, and the transfer rate. Segment design is clear and easy to understand without subnetworks. The gateway itself is confguration-free. All in all, these features significantly reduce engineering work.
SK1 supports any PROFIBUS DP master at a fixed transfer rate of 93.75 kbps.
