Siemens 6SN1111-0AA00-0DA1 Programmable Logic Controller Module

Siemens 6SN1111-0AA00-0DA1 is a line reactor for the Simodrive/Active Line Module family, not a programmable logic controller module. Designed for use with Simodrive 611 HF drives at up to 55 kW, this passive device adds inductance in the drive’s input path to help linearize current draw and damp switching transients, improving power quality and EMC performance. Verified specifications include a nominal line current (Aeff) of 103 A, a per-string voltage drop of 12.3 VAC, and an inductance of 0.27 mH, with a total weight of 18 kg. The part number is 6SN1111-0AA00-0DA1, and Siemens catalogs it as a spare part; the item is listed as no longer available and the documented successor is 6SN1111-0DV0 (partially compatible). This line reactor is part of the SINAMICS/SIMODRIVE drive ecosystem and is intended to accompany high-power motor loads where controlling grid disturbances is important, particularly during start-up and braking, without providing any control or logic functionality.
