Siemens 6ES7314-6BH04-0AB0 Programmable Logic Controller

Belonging to the CPU 314C-2 PtP product family, the Siemens 6ES7314-6BH04-0AB0 is part of the PM400: Phase Out Started lifecycle, ensuring continued support for existing installations. It features 4 high-speed counters (60 kHz) for rapid input signal processing, an integrated 24 V DC power supply, and a generous 192 KB work memory for complex control programs. Weighing 0.737 kg and measuring 13.10 × 15.40 × 13.10 cm, it fits comfortably in control cabinets while maintaining durability. Manufactured in Germany, it offers the precision engineering and build quality expected from Siemens. The unit requires a Micro Memory Card and uses dual 40-pole front connectors for streamlined wiring and modular expansion.

Marketed as the CPU 314C-2 PtP, it comes in a compact form with integrated MPI communication, making it ideal for machine builders and system integrators who require flexibility without large footprints. Key onboard features include 24 digital inputs, 16 digital outputs, 4 analog inputs, 2 analog outputs, and a dedicated Pt100 temperature input for precise thermal monitoring. The Siemens 6ES7314-6BH04-0AB0 also integrates an RS485 interface, allowing direct connection to serial devices and point-to-point communications in industrial environments.

In real-world applications, the Siemens 6ES7314-6BH04-0AB0 is suited for process control, high-speed machinery, temperature-critical systems, and mixed-signal automation environments. Its integrated Pt100 input eliminates the need for additional temperature modules, while the RS485 interface ensures seamless communication with barcode scanners, HMIs, drives, and legacy devices. The combination of digital, analog, and specialized I/O makes it an all-in-one controller for complex machines and distributed systems. Even in its PM400 lifecycle stage, the 6ES7314-6BH04-0AB0 CPU 314C-2 PtP remains a preferred choice for engineers who need proven reliability, flexibility, and strong Siemens ecosystem compatibility.
