Description
About the KTP400 Comfort
About the KTP400 Comfort
The Siemens 6AV2124-2DC01-0AX0 is a SIMATIC HMI KTP400 Comfort panel with a 4.3-inch TFT touchscreen (480 x 272 pixels, 16.7 million colors) plus 4 function keys with LEDs. It combines PROFINET, PROFIBUS/MPI, and USB interfaces with IP65 front protection for machine-level visualization and control, backed by 4 MB of configuration memory for projects built in WinCC Comfort V11 or later.

Selection Notes
The KTP400 Comfort's IP65 front rating with NEMA 4/4X approval fits panel-door mounting in washdown or outdoor-adjacent environments, while the rear-only IP20 rating means the enclosure interior must stay protected. Choose this model over a keypad-only panel when touch operation and PROFINET-based diagnostics are both needed on a single 4.3-inch screen; the 4 MB memory budget favors single- or few-screen projects rather than multi-recipe, graphic-heavy applications.
Applications
Used as a compact operator interface on packaging machines, conveyor sections, and standalone skids where panel space is limited to about 4 inches and PROFINET or PROFIBUS/MPI connects the panel to a SIMATIC PLC.
