The SIMATIC S7-300 CPU 313C is a compact controller designed for medium-performance automation tasks within the S7-300 platform. It integrates 24 digital inputs, 16 digital outputs, 4 analog inputs, and 2 analog outputs, plus support for one PT100 channel and three 30 kHz fast counters, reducing the need for separate I/O modules in space-constrained panels. An integrated 24 V DC power supply and 32 Kbyte working memory support typical machine and process applications. Communication is via MPI, and operation requires a Micro Memory Card for program storage. The unit uses front connectors (2 x 40-pin) for streamlined wiring and serviceability. Typical use cases include discrete manufacturing and small process skids where deterministic control, integrated I/O, and reliable Siemens S7 architecture are required. Packaging dimensions and net weight support panel design and logistics planning. Note that this part has reached end of product lifecycle, so planning for spares and migration is recommended.
