It's not a CPU or I/O module — it's the piece that manages the redundant PROFIBUS ring segments in a high-availability DP network. Width is 200 mm, depth is 57 mm, height is 100 mm. IP20 rating limits use to a protected enclosure. Supply range is 20.4 V DC to 28.8 V DC. The description labels this a spare part, consistent with the mature lifecycle stage. This module is for a redundant DP ring using PRB segments.","metaTitle":"Siemens 6ES7972-4AA50-0XA0 SIMATIC DP PRB Segment Controller","metaDescription":"Siemens 6ES7972-4AA50-0XA0 SIMATIC DP PRB segment controller, automatic change-over switch between PRB segments.
