SIEMENS 6ES7400-0HR51-4AB0 New and Original High quality

6ES7400-0HR51-4AB0

The 6ES7400-0HR51-4AB0 model product is a high availability redundant controller kit for the SIMATIC S7-400H system. It adopts a dual CPU 412-5H redundant architecture and integrates one UR2-H communication module, two PS 405 10A power modules (supporting DC 24/48/60V wide voltage input), four synchronization modules, and two 1-meter synchronous cables to achieve CPU level hot standby switching and millisecond level fault recovery. This kit builds a highly reliable industrial network using the PROFIBUS DP/PROFINET IO protocol, supports clock synchronization and data mirroring functions, and is suitable for scenarios such as process industries and rail transit that require strict system continuity. Its modular design is compatible with the S7-400 series I/O modules and can achieve a compact layout through rail installation. Paired with the TIA Portal engineering platform, it can complete the full lifecycle management from hardware configuration to fault diagnosis, while complying with the IEC 61508 SIL 3 functional safety standard and providing complete redundant system certification documents.
