In China, if you wish to purchase the in-stock Siemens 6AV2123-2DB03-0AX0 integrated 4.3-inch TFT color touch screen + function keys + PROFINET communication interface, welcome to Rayon Automation. It supports configuration through TIA Portal / WinCC Basic and is widely used in scenarios such as mechanical equipment, production lines, and automation control cabinets.
Compact design
Compared with large HMI devices, the 4.3-inch small-sized screen combined with the ultra-thin body structure saves the installation space of the control cabinet, and is suitable for the compact integration requirements of OEM equipment.
Touchscreen + physical button dual operation mode
To meet the strict requirements of industrial sites for the long-term reliable operation of equipment, the Siemens 6AV2123-2DB03-0AX0 adopts a combination design of touch screen and function buttons. For complex parameter input, menu switching, status monitoring and formula setting, the function buttons are specifically used for quick start/stop, manual control and emergency operations, thereby improving operational efficiency.
Standardized communication and excellent connectivity
Standardized with an industrial Ethernet PROFINET interface, it supports high-speed and stable data exchange with Siemens and third-party devices that support the PROFINET protocol, easily integrating into existing industrial networks, enabling remote monitoring and data collection of equipment, and providing interfaces for digital upgrades.
High cost-effectiveness and balanced functionality
As a Basic series product, it has stripped away complex advanced functions and supports 65,536 color displays (with clearer graphics), formula management (facilitating multiple product switching), alarm views (clearly showing faults), and data recording (exportable to a USB drive via USB), fully capable of meeting the monitoring needs of most basic automation equipment.
