The 4.3 inch SIMATIC HMI KP400 and KTP400 Comfort (6AV2124-1DC01-0AX0) represent the pinnacle of compact human-machine interface technology, engineered by Siemens for demanding automation tasks. As the mounting-compatible successors to the OP77B and TP177 4.3 inch, these panels deliver superior performance, enhanced functionality, and a significantly higher screen resolution. The KP400 model excels in applications requiring mechanical keys within cramped spaces, while the KTP400 offers a touch-screen solution for space-constrained environments. Both units are built with robust industrial-grade components, ensuring reliable operation in extreme conditions. With a 4.3-inch TFT widescreen display, 16 million colors, and a 480 x 272 pixel resolution, operators gain clear, real-time data visualization. The devices support extensive software features including 4000 messages, 500 process pictures, 1024 variables, and 100 recipes, all configurable via WinCC Comfort (TIA Portal). Designed for seamless integration into PROFINET and PROFIBUS networks, this HMI family is ideal for machine builders and system integrators seeking high-end performance in a compact footprint.
