CBE20 communication board for documented PROFINET IO drive integration
Siemens 6SL3055-0AA00-2EB0 is the SINAMICS S120 CBE20 communication board. Siemens describes the exact item as a painted PROFINET module for connection to PROFINET IO, with four RJ45 ports and switch functionality. It is a communication option for a supported drive-control arrangement, not a stand-alone Ethernet switch. Before ordering, verify the complete suffix, installed SINAMICS control unit, firmware, PROFINET configuration and the existing option board. The Siemens Industry Mall currently labels this order number PM300 Active Product. Stockoems can review label photographs, commercial condition and supply availability for the requested quantity. Our team coordinates protective packaging, shipping documents, tracking and worldwide delivery, subject to a technical compatibility review.
Condition, availability and warranty are Stockoems commercial terms, not Siemens manufacturer commitments.
