Product overview

The Siemens 6ES7972-0AA02-0XA0 is a RS485 Repeater for PROFIBUS/MPI used for regenerating and segmenting profibus or mpi networks. Typical applications include profibus segment extension and mpi network segmentation.

Selection must follow the complete Siemens article number rather than appearance alone. Before ordering, confirm profibus/mpi baud rate and topology, segment lengths and node count, termination and equipotential bonding, 24 v supply and cabinet mounting.

COMMON APPLICATIONS

Installed-system context

  • PROFIBUS segment extension
  • MPI network segmentation
  • Galvanically isolated bus branches

Tell us the controller, communication network and installed panel details. That context helps prevent a visually similar but incompatible replacement.
