Siemens 6AV2123-2DB03-0AX0

The Siemens 6AV2123-2DB03-0AX0 is a SIPLUS-rated KTP400 Basic Color HMI designed for reliable operator control and visualization in harsh industrial environments. Built on the standard KTP400 Basic platform and enhanced with conformal coating, this panel is well-suited for applications where temperature extremes, humidity, or airborne contaminants are a concern.

Featuring a 4-inch TFT color display with 65,536 colors, the HMI provides clear, intuitive visualization for machine status, alarms, and basic process control. The integrated PROFINET interface enables seamless communication with Siemens PLCs, making it an ideal choice for S7-1200 and S7-1500-based systems that require dependable operator interaction at the machine level.

With an extended operating temperature range of −20°C to +60°C, this SIPLUS HMI is commonly used in outdoor enclosures, unconditioned control cabinets, and industrial settings where standard HMIs may not be sufficient. Its compact form factor and proven Siemens reliability make it a strong option for retrofits, replacements, and new installations where durability and long-term availability matter.
