Overview
The 6AG1972-0AA02-7XA0 is a Siemens SIPLUS DP RS-485 repeater for PROFIBUS/MPI bus systems, based on the standard 6ES7972-0AA02-0XA0 with conformal coating applied. It supports transmission rates from 9.6 kbit/s to 12 Mbit/s and connects up to 31 nodes per segment. The module operates on a 24 V DC supply from the terminal module and is rated IP20. Dimensions are 45 mm wide, 128 mm high, and 67 mm deep.
Lifecycle
The 6AG1972-0AA02-7XA0 is in phase-out status with a discontinuation date of 2025-05-02. For ongoing applications, evaluate the standard SIMATIC 6ES7972-0AA02-0XA0 as a same-function alternative — it lacks conformal coating but remains in active production.
