Product description

The Siemens SIMATIC S7-400H CPU 412-3H (6ES7412-3HJ14-0AB0) is a central processing unit designed for the high-availability S7-400H and fail-safe S7-400F/FH systems. This CPU offers 768 KB of memory, divided into 256 KB for data and 512 KB for programs, ensuring robust performance for critical automation tasks.

It features three communication interfaces: one MPI/DP interface for standard communication and two additional interfaces specifically for synchronization modules, essential for redundant operation. This redundant design ensures continuous operation even in the event of a single CPU failure, making it ideal for processes where downtime is unacceptable.
