The Siemens 6ES7400-0HR01-4AB0 is a pre-configured S7-400H system bundle featuring the powerful CPU 412-5H units. This H-redundant system includes 1 x UR2-H rack (without memory card), 2 x PS407 UC120/230V power supplies (10 A each), 4 x synchronization modules with 10-meter capability, 2 x sync cables (1 m), and 2 x CPU 412-5H processors. For full deployment, users must additionally procure 2 memory cards and 4 backup batteries. Designed for high-availability applications, the system is part of the CPU 412H product family.
Weighing approximately 30.40 kg and packaged in a volume of 59.10 x 28.00 cm, this industrial-grade bundle is built for scalability, robustness, and uninterrupted operation. Unlike smaller systems, the S7-400H platform supports hot standby functionality, ensuring seamless CPU switchover during hardware failures. This model is currently in the PM300 Active Lifecycle, making it a preferred choice for process automation in power plants, oil & gas, pharma, and transport infrastructure.
The Siemens 6ES7400-0HR01-4AB0 PLC bundle is purpose-built for industries that require uninterrupted process control and fail-safe redundancy—such as energy management systems, metro rail automation, power generation plants, and high-volume manufacturing lines. With built-in H-redundancy and real-time synchronization, it ensures zero downtime and consistent data integrity, even during component failures.
For Indian system integrators and engineering firms building high-reliability systems, this S7-400H bundle eliminates the need to source components individually and guarantees Siemens-certified compatibility. Its modular structure allows future expansion and tight coupling with SCADA, PCS 7, or safety systems. Engineers working with hazardous process environments often prefer this H-system setup to comply with redundancy and safety regulations.
Whether you’re setting up a new process control environment or upgrading an aging infrastructure to a fault-tolerant platform, the Siemens 6ES7400-0HR01-4AB0 delivers long-term performance, seamless integration, and unmatched reliability across critical industries.
