Siemens SIMATIC S7-300 CPU 313C-2 DP Compact PLC – 6ES7313-6CG04-0AB0

The Siemens SIMATIC S7-300 CPU 313C-2 DP (6ES7313-6CG04-0AB0) is a compact programmable logic controller designed for industrial automation and machine-control applications. It combines CPU processing, integrated digital inputs and outputs, high-speed counting functions, and a PROFIBUS DP interface in a single compact unit.

With 128 KB of work memory, 16 digital inputs, 16 digital outputs, and three integrated high-speed counters supporting frequencies up to 30 kHz, this CPU is suitable for automated machinery, production lines, and distributed control systems. Its MPI communication capability and integrated PROFIBUS DP interface support communication with compatible SIMATIC controllers and distributed I/O equipment.
