It supports transmission rates from 9.6 kbit/s up to 12 Mbit/s, auto-sensing the baud rate of the segment it is inserted into. This is the SIPLUS variant with conformal coating per IPC-CC-830A Class A, making it suitable for environments with condensation, corrosive gases, or salt spray — not a standard indoor-only part. ## Temperature range and environmental tolerance The conformal coating and Type 1 fouling protection per EN 60664-3 mean it tolerates humidity, dust, and aggressive atmospheres better than the base model. The unit also carries qualification to ANSI/ISA-71.04 for process environments — Level GX Group A/B (excluding trichlorethylene), Level LC3 salt spray, and Level LB3 oil resistance. This is the spec that matters for chemical plants, offshore platforms, or food processing zones. ## Power and connection requirements Supply voltage is 24 V DC nominal, with a permissible range of 20.4 V to 28.8 V DC. The repeater draws up to 100 mA without load at the PG/OP socket; with a 24 V / 100 mA load on that socket, total draw reaches 200 mA. Electrical connection for supply voltage is via a terminal module; PROFIBUS cables connect through two terminal blocks. The housing is IP20, so it mounts inside a control cabinet or junction box — not exposed to direct washdown. ## Lifecycle status and sourcing note This part carries a manufacturer status of NRND (Not Recommended for New Designs). It remains available for existing installations and BOM lines, but new projects should evaluate the standard 6ES7972-0AA02-0XA0 or current-generation PROFIBUS repeaters.","metaTitle":"Siemens 6AG1972-0AA02-7XA0 SIPLUS DP RS-485 Repeater","metaDescription":"Siemens 6AG1972-0AA02-7XA0 SIPLUS DP RS-485 repeater, 12 Mbit/s, 24 V DC, IP20, -25 to +70 °C, conformal coated.
