The Siemens SIMATIC S5 CPU 928B (6ES5928-3UB11) is a rugged, industrial-grade central processing unit engineered to handle highly sophisticated automation and process control tasks. Serving as a central pillar for SIMATIC S5-135U/155U rack configurations, this processor module executes fast cycle times, controls complex mathematical algorithms, and easily manages extensive I/O systems.

With the inclusion of an expansion interface module slot, the CPU 928B enables legacy factory networks to scale communication seamlessly across V.24 (RS-232C), RS-422A/485, and SINEC L1 local area architectures. Whether applied in modern legacy retrofits or maintaining automated manufacturing lines, this controller stands as a testament to precision German engineering and long-term automation reliability.

Optimized Architecture: Purpose-built for high-performance processing within legendary Siemens S5-135U and S5-155U programmable logic controller (PLC) systems.
Expandable Dual-Interface Support: Includes an integrated slot for a 2nd communication interface module, providing modular flexibility for multi-device environments.
High-Speed Execution: Designed with advanced internal user memory processing, containing 46 KB internal DB RAM for user data alongside up to 64 KB external memory mapping options.
Industrial Grade Communication: Outfitted with a primary 20 mA current loop (TTY) interface via a heavy-duty 15-way Cannon socket for seamless PG/OP/PC connectivity.
Robust Diagnostic LEDs: Built-in front-facing fault indicator lights streamline maintenance by offering rapid visual diagnostics of RUN/STOP operational status.
