Siemens 6ES7412-2XJ05-0AB0 Central Processing Unit

Product Description

The Siemens 6ES7412-2XJ05-0AB0 is a CPU 412‑2 central processing unit engineered for medium-scale automation applications, offering enhanced performance over earlier 412 series models. It delivers reliable processing, dual integrated communication interfaces, and flexible memory management, enabling seamless control in industrial automation and process control systems.

Equipped with 512 KB of work memory (split evenly between code and data), the 6ES7412-2XJ05-0AB0 supports larger and more complex control programs. Memory expansion via MMC (Micro Memory Card) ensures adaptability for evolving automation needs. Dual MPI/DP ports allow direct PROFIBUS connectivity for distributed I/O, HMIs, and other networked controllers.

The CPU supports global data exchange, S7 communication, PG/OP connections, and isochronous mode for PROFIBUS, making it compatible with synchronized process operations. Rated for 24 V DC supply via the S7‑400 system power module, it operates reliably in industrial environments with operating temperatures from 0 °C to 60 °C.

Designed for S7‑400 racks, the compact module allows easy integration alongside other PLC modules and ensures long-term service in demanding industrial applications. It is fully backward-compatible with legacy 412 systems and can be substituted with model 6ES7412-2XK07-0AB0 if required.
