Siemens 6ES7 314 CPU Standard Controller With Memory Card

Siemens 6ES7314-1AG14-0AB0 SIMATIC S7-300 CPU 314 is a compact central processing unit for the SIMATIC S7-300 family, featuring an integrated 24 V DC power supply and MPI interface for programming and device communication. It provides 128 KB of working memory, enabling fast execution of ladder logic and data handling for small control tasks. Micro Memory Card usage is optional for this variant, with the MMC not required for operation. The CPU integrates into standard S7-300 backplane systems and works with compatible I/O modules to perform straightforward automation routines, sequencing, timing, and basic data processing. The 24 V DC input aligns with common industrial panel power standards, and the compact form factor supports installation in standard control cabinets. This CPU is commonly deployed in small machine control projects and automation cells where MPI connectivity and local processing are sufficient for reliable, entry‑level control tasks.
