Product details

The Siemens 6AG1123-2MA03-2AX0 is an industrial automation component featuring built-in MPI, PROFIBUS, and MODBUS RTU (Modicon) communication. It includes a local operator interface with buttons, a buzzer, and switches, housed in a plastic enclosure rated IP20 at the rear. Operating range spans -20 °C to 60 °C, making it suitable for control cabinets without temperature regulation.

Operator interface

Buttons, buzzer, and switches provide a bare-minimum operator interface for status indication and local control. The plastic housing and IP20 rear suggest panel-mount or DIN-rail installation. No touch screen or graphical display; all interaction is through physical inputs and acoustic feedback. The device also supports icons and flash memory for local data (arrays, recipes).
