More Information

Overview Manuals Segment Changeover DC Supply Path Cabinet Placement Status Check

Features:

  • Automatic change-over selects between PRB segment paths.
  • The 20.4 to 28.8 V DC input powers the monitoring and switching electronics.
  • The IP20 housing is intended for protected cabinet installation.
PRB segment connections enter the controller as separate network paths.

The internal logic evaluates the documented operating condition and applies the automatic change-over function.

The selected path continues the SIMATIC DP segment connection while the enclosure protects the electronics.

The Siemens 6ES7972-4AA50-0XA0 SIMATIC DP PRB Segment Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6ES7972-4AA50-0XA0 PRB Segment Controller Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Selecting the active PRB network path automatically

  • Incoming paths: The PRB segments remain separate before the selection point.
  • Change-over logic: The controller applies the documented automatic switching function.
  • Selected path: The active segment continues toward the connected SIMATIC DP network.
  • Network role: The unit controls segment selection rather than serving as a general I/O module.

Powering monitoring and switching from one DC input

  • Lower boundary: The supply remains at or above 20.4 V DC.
  • Upper boundary: The supply remains at or below 28.8 V DC.
  • Internal load: The input feeds both supervision and change-over electronics.
  • Cabinet source: Conductor protection follows the documented DC installation.

Keeping the segment controller inside its installation limits

  • Enclosure: IP20 requires a protected cabinet location.
  • Width: The product body occupies 200 mm across the mounting plane.
  • Height: The controller body is 100 mm high.
  • Depth: A 57 mm product depth must remain clear for installation.

Tracing a segment fault before changing network hardware

  • Supply state: Confirm the DC input remains inside the permitted range.
  • Segment path: Check each PRB segment independently at the controller.
  • Connection order: Keep the incoming and outgoing network roles aligned.
  • Change-over result: Verify that the selected path corresponds to the documented operating condition.
Description
Siemens 6ES7972-4AA50-0XA0 is a SIMATIC DP PRB segment controller whose system responsibility is to perform automatic change-over between PRB segments. It monitors the available segment path and transfers the connection without turning the unit into a general-purpose PROFIBUS repeater.

Power for 6ES7972-4AA50-0XA0 enters through a 20.4 to 28.8 V DC supply range, which feeds the electronics that supervise and operate the segment switch. The IP20 enclosure places the controller inside a protected cabinet rather than on an exposed field network.

Installed between the PRB network sections, 6ES7972-4AA50-0XA0 keeps the incoming and outgoing segment roles distinct while applying its automatic change-over function. Its 200 mm by 100 mm by 57 mm product envelope determines the cabinet space required around those network connections.

Technical notes
Within the documented DC range, the automatic switching logic of Siemens 6ES7972-4AA50-0XA0 selects the applicable PRB segment path.
