Function

The FieldConnex® basic Segment Coupler is an all-in-one gateway and fieldbus power supply for connecting PROFIBUS PA to PROFIBUS DP
transparently. The power output suits long cable lengths and high device counts. 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.

Availability and a long service life are achieved through a passive impedance filter and a design optimized for low heat dissipation. The fieldbus
diagnostic handheld (FDH‑1) connects directly to test plug sockets located on the plug-in terminal.
