Siemens 6ES7 412-3HJ14-0AB0 SIMATIC S7-400 CPU 412-3H redundancy-capable central processing unit.

The Siemens 6ES7 412-3HJ14-0AB0 is a CPU 412-3H central processing unit designed for the SIMATIC S7-400 programmable logic controller platform. This high-availability processor module supports H-system (redundant) configurations, providing fault-tolerant automation control for applications where system uptime is critical.

The CPU 412-3H is engineered for redundant S7-400H systems, enabling seamless bumpless switchover between paired CPUs in the event of a fault. It is typically deployed in process automation, manufacturing, and industrial control environments where continuous operation is essential, including chemical plants, power generation facilities, and critical infrastructure.

This is a legacy product within the Siemens SIMATIC portfolio, with the S7-400 series now superseded by newer platforms such as S7-1500. However, the 6ES7 412-3HJ14-0AB0 remains in demand for maintaining and expanding existing S7-400H installations across industrial sites worldwide.
