Siemens 6ES7314-6EH04-0AB0 Programmable Logic Controller Module

Siemens 6ES7314-6EH04-0AB0 is a SIMATIC S7-300 CPU module (CPU 314C-2) that delivers compact, integrated control for manufacturing and process environments. Installed on an S7-300 backplane rack and powered by 24 V DC (via the PS 307 supply), it provides 24 digital inputs, 16 digital outputs, 4 analog inputs, 2 analog outputs, and 1 Pt100 input for mixed sensing tasks, with embedded program and data memory. Communication options include MPI/PROFIBUS DP through a built-in port and PROFINET Ethernet for higher‑level interfacing, while high‑speed counters are supported for precise sequencing. Visible indicators—RUN, STOP, ERROR, and BUS status LEDs—facilitate quick diagnostics in rugged industrial settings, and the IP20 enclosure rating suits typical control panel installations. This CPU excels in machine and process PLC control with its integrated I/O, serving applications from manufacturing automation and process control to material handling, packaging lines, water/wastewater treatment, and building automation, where standalone control or straightforward retrofit into a passive S7‑300 ecosystem is desired.
