The Siemens 6AG1972-0AA02-7XA0 is a SIPLUS DP RS-485 repeater based on the standard 6ES7972-0AA02-0XA0. It is designed to connect and extend PROFIBUS or MPI bus systems by regenerating RS-485 communication signals between separate bus segments.
The repeater supports transmission rates from 9.6 kbit/s to 12 Mbit/s and supports up to 31 nodes per connected segment. It operates from a 24 V DC supply and provides two PROFIBUS cable terminal blocks together with a PG/OP interface. The SIPLUS version adds conformal coating and an extended operating temperature range of approximately -25 °C to +70 °C for demanding industrial environments.
