Product details

HMI panel with PROFINET connectivity

The Siemens 6AG1123-2JB03-2AX0 is a SIMATIC HMI panel that connects to automation controllers over PROFINET, with MODBUS TCP/IP support for multi-vendor integration. Its rated operating temperature range of -20 to 60 °C suits unheated plant-floor environments, and the IP20 rear protection allows flush mounting in a standard control cabinet.

The panel mounts into a standard cutout; the IP20-rated rear enclosure protects internal electronics from particle ingress behind the panel. Icons and libraries expedite screen development.
