Siemens AG 6FX1126-1AA04 Printed Circuit Board

Siemens AG 6FX1126-1AA04 is a monochrome video graphics Printed Circuit Board designed for SINUMERIK 800 CNC controls. This video board sits in the control’s display subsystem and directly drives the operator interface output visible on the SINUMERIK monitor rack, rendering monochrome graphics and text for menus, status indicators, and diagnostic messages. As an original Siemens component, the 6FX1126-1AA04 is used as a replacement part within SINUMERIK 800 family configurations that require a dedicated video interface between the CNC controller electronics and the display unit. In typical SINUMERIK 800 installations, the board enables the machine operator to interact with the control via the monochrome display, supporting essential tasks from menu navigation to fault diagnosis. The part number is commonly encountered in spare parts catalogs and repair listings for SINUMERIK 800 CNC modules, reflecting its role as the dedicated video graphics board for legacy Siemens CNC displays.
