Nine-inch key-and-touch operation for flexible industrial machine control.
The Siemens 6AV2125-2JB03-0AX0 is a SIMATIC HMI KTP900 Mobile operator panel for flexible machine-side visualization and control. Its 9.0-inch TFT display provides 800 × 480 pixel resolution and 16 million colors. Operators can use the touch surface together with ten function keys. Communication is provided through one PROFINET/Industrial Ethernet interface, while one multimedia-card slot and one USB interface support project and service workflows. Siemens specifies configuration from WinCC Comfort V13 SP1. Procurement teams should compare the complete suffix, cable and connection concept, project backup, engineering version, interface requirements and configured controller before replacement.
