It is listed as a spare part, not a standard production module, so it is intended for replacement of an existing unit in a live line rather than new design-in. The amplifier supports a maximum baud rate of 500 kbit/s, which is the standard speed for PROFIBUS-DP on long collector-wire runs. That rate is sufficient for most distributed I/O and drive applications on a moving gantry or rotating table where a conventional cable would wear. ## Integration note Mounts on the SIMATIC DP power rail in the same slot as a standard DP slave. The collector-wire input connects to the amplifier's bus terminals; the amplified output feeds the next segment. No external power supply is needed — it draws its power from the rail itself.","metaTitle":"Siemens 6ES7972-4AA01-0XA0 Power Rail Booster, PROFIBUS-DP,","metaDescription":"Siemens SIMATIC DP power rail booster signal amplifier for PROFIBUS-DP over collector wires, max 500 kbit/s.
