Siemens 6SN1112-1AB00-0BA0 Programmable Logic Controller Module

Siemens 6SN1112-1AB00-0BA0 is a SIMODRIVE 611 capacitor module that attaches to the DC link to provide energy storage for power-backup in Siemens drive systems. It features a 4.1 mF capacitor module and measures 100 mm in width, 480 mm in height, and 211 mm in depth (W × H × D), designed for the SIMODRIVE 611 family. Each module stores about 252 watt-seconds of energy at the specified DC-link voltage, helping maintain a stable bus during short interruptions and ensuring smooth operation of connected equipment. The 6SN1112-1AB00-0BA0 designation identifies this exact capacitor module variant used for DC-link backup connections, making it a specialized spare part for retrofit or repair of SIMODRIVE 611 drives in industrial automation setups. Typical applications include CNC machinery, packaging lines, and other motion-control configurations that rely on reliable DC-link power during transient events.
