6ES7414-4HM14-0AB0 SIEMENS Central Unit Module

SIEMENS 6ES7414-4HM14-0AB0 Central Unit Module

Product Description:

The SIEMENS 6ES7414-4HM14-0AB0 is a high-performance central processing unit (CPU) from the Siemens SIMATIC S7-400 series, specifically the S7-400H fault-tolerant line. This powerful and robust PLC processor is engineered for applications requiring maximum availability and reliability in demanding industrial environments, such as process industries, energy generation, and critical infrastructure. Its primary role is to provide redundant control, ensuring continuous operation even in the event of a hardware failure.

A defining feature of this CPU 414-4H is its fault-tolerant design, which requires it to be used in a paired configuration. The two CPUs operate in synchronism, continuously monitoring each other. If one CPU fails, the other automatically assumes full control of the process without any interruption, thereby preventing costly downtime. This module is equipped with integrated PROFIBUS and PROFINET interfaces, allowing it to manage complex and extensive I/O systems and communicate seamlessly with other automation components. With its significant work memory and fast processing speeds, it is capable of handling large-scale programs and complex data processing tasks, making it an ideal solution for high-availability control systems.

Technical Specifications Reference:

The SIEMENS 6ES7414-4HM14-0AB0 is a fault-tolerant S7-400H CPU with a work memory of 2.8 MB for the user program. It features a combined MPI/PROFIBUS DP interface and an integrated PROFINET interface with two ports. The PROFINET interface supports RT (Real-Time) communication for deterministic response times in distributed automation networks. This CPU supports a substantial I/O configuration, capable of handling up to 65,536 digital I/O points and 4,096 analog I/O points.

The module is designed for operation on a 24 V DC power supply and must be installed in a dedicated S7-400 UR2-H rack. It operates within an ambient temperature range of 0 to 60 degrees Celsius. The CPU requires a backup battery for memory retention of the RAM in case of a power loss. It is compliant with key international standards for safety and industrial automation, carrying the CE, UL, and cULus marks, which certify its suitability for global deployment in demanding industrial settings.
