Siemens 6ES7400-0HR51-4AB0

The Siemens 6ES7400-0HR51-4AB0 is a SIMATIC S7-400H system bundle designed for high-availability applications. This package includes two CPU 412-5H units, two PS 405 power supplies rated at 10A for 24/48/60 V DC, and synchronization components such as four sync modules and two 1-meter sync cables, allowing for precise coordination across the system. Notably, this bundle does not come with memory cards, so additional memory cards and backup batteries are necessary for full operation. Distributed by BSP Automation, this system is well-suited for environments that demand reliable, fault-tolerant control solutions.
