Siemens 6ES7 313-5BF03-0AB0 Compact CPU Module

Siemens 6ES7-313-5BF03-0AB0 Compact CPU Module (CPU313C) is a compact SIMATIC S7-300 controller that consolidates 24 digital inputs and 16 digital outputs, 4 analog inputs, 2 analog outputs, and 1 Pt100 temperature input into a single module. It features two 40‑pole front connectors, an integrated 24 V DC power supply, and MPI communication for programming and data exchange with other Siemens devices. The unit provides 64 KB of working memory for running small to mid‑size automation programs and data, along with three high‑speed counters capable of up to 30 kHz for fast counting and timing tasks. This CPU is designed for use in SIMATIC S7-300 backplane configurations and, according to manufacturer documentation, requires a Micro Memory Card for program storage. Ideal for compact machines that combine digital and analog I/O with temperature sensing, the 313C CPU supports typical control tasks in packaging lines, small process controls, and straightforward automation applications.
