The SIEMENS SIMATIC S7-400H, CPU 412-5H (6ES7412-5HK06-0AB0) is a central processing unit engineered for high-availability and fail-safe automation architectures. This CPU is the core of redundant S7-400H systems, ensuring uninterrupted operation even in the most demanding industrial environments. With its five versatile interfaces—including MPI/DP, DP, PROFINET, and two sync module ports—it enables flexible integration into existing networks and supports seamless synchronization between redundant CPUs. The 1 MB memory allocation (512 KB for program and 512 KB for data) provides ample capacity for complex control sequences, while the built-in PROFINET interface facilitates modern industrial communication and remote diagnostics. Ideal for applications requiring maximum uptime, such as power generation, water treatment, and discrete manufacturing, the CPU 412-5H delivers deterministic performance with hot-swap capability. Each unit is 100% original, factory-tested, and available for expedited shipping worldwide.
