Siemens 6AG1647-0AH11-2AX1 SIPLUS HMI KTP400 Basic

The Siemens SIPLUS HMI 6AG1647-0AH11-2AX1 is a ruggedized variant of the SIMATIC KTP400 Basic panel, belonging to the SIPLUS extreme product line designed for use in harsh and demanding environmental conditions. This 4-inch Basic Panel combines key-and-touch operation and is engineered to withstand extended temperature ranges, increased condensation, and exposure to corrosive atmospheres. It is part of the SIMATIC HMI Basic Panels generation and is configured and operated using the WinCC Basic engineering software integrated in TIA Portal.

The 6AG1647-0AH11-2AX1 features a 4-inch TFT widescreen display with a resolution of 480 x 272 pixels and 64,000 color depth, supporting both touch and 4 function key operation. Communication is provided via a PROFINET interface, enabling direct integration into standard Ethernet-based automation networks. The panel offers 10 MB of user memory for project data, supports Siemens S7-1200 and S7-1500 PLC families, and operates from a 24 V DC supply. As a SIPLUS extreme variant, it is coated and treated to resist condensation, corrosive gases, and biological influences beyond the standard SIMATIC specification.

This panel is commonly deployed in industries such as chemical processing, water and wastewater treatment, food and beverage, and offshore or marine environments where standard HMI panels would be susceptible to environmental degradation. Its ruggedized design makes it suitable for installation in control cabinets exposed to high humidity, temperature fluctuations, and chemically aggressive atmospheres. The compact 4-inch form factor and combined key-and-touch interface make it well suited for machine-level operator panels where space is limited and reliable operation under adverse conditions is required.
