The 6ES7314-6CH04-0AB0 is a highly integrated CPU 314c-2 DP compact central processing unit belonging to the globally proven SIMATIC S7-300 PLC system. This controller is specifically engineered for space-critical applications and automation tasks that require high-density local I/O handling, rapid bit processing, and deterministic fieldbus communication.
Built-in 4-channel hardware high-speed counters up to 60 kHz
Simultaneously integrated dual interfaces: MPI and PROFIBUS DP
Four-in-One Integration: Combining PLC Brain, Digital I/O, Analog I/O, and Temperature Detection
Equipped with a robust 192 KB built-in work memory, this CPU delivers exceptional processing power to execute complex control program logic, advanced data handling, and technological instructions smoothly. As a "Compact" variant, its core strength lies in its remarkable out-of-the-box hardware integration. A single module houses a comprehensive array of built-in factory I/O, including 24 Digital Inputs (DI) and 16 Digital Outputs (DO) for discrete machine control, alongside 4 Analog Inputs (AI) and 2 Analog Outputs (AO) to interface with sensors and actuators seamlessly. Furthermore, it features 1 dedicated Pt100 RTD channel for direct high-precision temperature monitoring without requiring specialized thermal modules. For advanced motion control and high-frequency signal processing, the CPU 314C-2 DP integrates 4 onboard high-speed counters (HSC) supporting frequencies up to 60 kHz. This makes it an ideal choice for tasks like precise rotary encoder reading, frequency measurements, pulse-width modulation (PWM), and basic single-axis positioning.

When using the Siemens 6ES7314-6CH04-0AB0 compact CPU, it is critical to properly configure and shield the integrated high-speed counters and analog I/Os to prevent electrical noise interference. Ensure adequate panel ventilation to manage heat dissipation from the high-density onboard electronics, and verify that the 24V DC power supply is stable and correctly fused. Additionally, since this legacy S7-300 hardware relies on STEP 7 V5.5 or TIA Portal for engineering, keep a dedicated Micro Memory Card (MMC) installed for program storage, as the CPU will not retain memory without it.
6ES7314-6CH04-0AB0 is the CPU 314C-2 DP compact PLC central processing unit of the Siemens SIMATIC S7-300 series. Featuring 192 KB of built-in work memory, this single module highly integrates a rich array of local I/O, including 24 DI / 16 DO, 4 AI / 2 AO, and 1 Pt100 channel. It comes equipped with integrated MPI and PROFIBUS DP bus interfaces, while also supporting technological functions such as 4-channel 60 kHz high-speed counting. Operation of this module strictly requires a Micro Memory Card (MMC) and two 40-pin front connectors.
