Siemens 6ES7412-2XJ05-0AB0 CPU Module SIMATIC S7-400

Siemens 6ES7412-2XJ05-0AB0 is a CPU412-2 central processing unit for the SIMATIC S7-400 distributed automation system. It provides 512 KB of working memory (256 KB for code and 256 KB for data) and features two communication interfaces: MPI/DP at 12 Mbit/s for programming devices and inter-controller communication, and a PROFIBUS DP interface for connecting DP field devices. As a member of the S7-400 family, this module handles control logic for mid-to-large automation tasks and integrates with Siemens I/O racks and networked devices, delivering deterministic execution in industrial environments. The CPU412-2 configuration supported by this module enables standard control tasks such as sequencing, data exchange, and reliable communication over MPI/DP and PROFIBUS DP networks, making it suitable for applications like manufacturing lines, packaging systems, conveyors, and flexible automation cells that rely on Siemens fieldbus protocols. With its 512 KB of RAM split between code and data, the unit provides adequate space for moderate program complexity and data storage within distributed control architectures.
