Siemens 6ES7401-2TA01-0AA0 is the SIMATIC S7-400 CR2 central rack. It provides eighteen module slots arranged in two segments. The peripheral bus is separated between these segments. The communication bus runs across both segments. The rack permits the installation of redundant power supplies.
The 6ES7401-2TA01-0AA0 provides the mounting and backplane structure for a compatible S7-400 assembly. The segmented arrangement must be considered when assigning modules. Power-supply placement and loading should be checked in the system design. It is a rack assembly rather than a CPU or a populated control station. This Siemens CR2 central rack supports a properly planned S7-400 hardware configuration.
Provide the central rack and backplane structure for a compatible SIMATIC S7-400 system.
Arrange modules with attention to the separated peripheral buses and the continuous communication bus.
Use the permitted power-supply arrangement while checking placement, loading and redundancy requirements.

Company was founded in Xiamen, Fujian, China, in 2005 with a team of only four people. At that time, we mainly served selected European and North American markets, supplying commonly requested industrial automation products from Siemens, Allen-Bradley and Bently Nevada. Although the business was still developing and we completed relatively few orders, this period helped us build essential product knowledge and international trade experience.
By 2017, our team had grown to approximately 30 people, and we had established a warehouse for in-stock automation components. Our business expanded across Europe, North America and Southeast Asia, while our product range grew from popular models to scarce and discontinued industrial automation parts. As our product knowledge and service experience increased, we completed nearly 20 orders per month on average.
Today, Company serves customers worldwide with a professional team of approximately 60 people. Our warehouse holds a broad selection of industrial automation components, including popular products, hard-to-find parts and discontinued models. We now complete more than 30 orders per month, with an average monthly transaction value of approximately USD 3 million. We have established long-term partnerships with nearly 30 customers from different countries and welcomed almost 40 international customers to visit our company.
Since our company was founded, we have served every customer with sincerity and professionalism. Our prices may not always be the lowest, but we earn long-term trust through quality products, dependable after-sales support, honest condition reporting, timely communication and responsible delivery. Our goal is to build lasting partnerships rather than pursue one-off transactions.
