Siemens 6ES7417-4HT14-0AB0 High-End Central Processing Unit

Product Description

The Siemens 6ES7417-4HT14-0AB0 is a high-end CPU 417‑4H module from the S7‑400 series, engineered for large-scale automation projects and high-availability systems. As one of the most powerful S7‑400 processors, it offers extensive memory, multiple communication interfaces, and redundancy features for mission-critical industrial operations.

With 4 MB of work memory expandable via MMC (Micro Memory Card), the 6ES7417-4HT14-0AB0 can execute highly complex control programs, handling vast distributed I/O networks efficiently. Four integrated MPI/DP interfaces provide robust PROFIBUS connectivity, supporting communication with distributed I/O modules, HMIs, and additional controllers.

Designed for redundancy (H‑systems), this CPU ensures uninterrupted operation even during hardware failures, making it ideal for systems where downtime is unacceptable. With a fast cycle time of approximately 0.05 µs per instruction, it delivers high-speed processing and reliability in demanding environments.

Engineered for industrial conditions, the 6ES7417-4HT14-0AB0 integrates seamlessly into S7‑400 racks, providing robust performance for large chemical plants, energy systems, factory automation, and infrastructure requiring high-availability control.
