The SIEMENS SIMATIC S7-300 CPU 314 IFM COMPACT CPU with MPI (Order No. 6ES7314-5AE01-0AB0) is a robust, integrated controller designed for demanding industrial environments. Combining a central processing unit with on-board digital and analog I/O, this compact CPU eliminates the need for separate interface modules, simplifying cabinet wiring and reducing overall system cost. Its 24 KB working memory and high-speed bit processing (approx. 0.1 µs per bit operation) make it ideal for real-time control in chemical, electronics, and general automation applications. The built-in MPI port enables direct connection to programming devices and other S7-300 stations, while the integrated 24 V DC power supply (19.2 V to 28.8 V range) ensures stable operation. Backed by Siemens’ proven reliability, this unit supports up to 512 digital I/O and 64 analog I/O via expansion racks, and is fully programmable with STEP 7 V5.5+ SP1 or TIA Portal (via compatible hardware).
