Siemens 6ES7412-3HJ14-0AB0 is the SIMATIC S7-400H CPU 412-3H central processing unit for S7-400H and S7-400F/FH systems. The replacement part provides 768 KB memory, divided into 256 KB data and 512 KB program memory, plus three interfaces: one MPI/DP interface and two interfaces for synchronization modules. It is intended for redundant or fault-tolerant automation architectures where the installed hardware pairing and project configuration are critical. Before replacement, verify the complete order number, hardware revision, synchronization modules, MPI/DP network, rack position, partner CPU, memory requirements, engineering project and label photographs.
