Siemens 6FX1126-1AA03 Safety Relay Module 24V DC

Siemens 6FX1126-1AA03 Sinumerik video graphics monochrome module is a replacement circuit card for Sinumerik CNC controls, providing the monochrome video graphics output used by the operator interface. Designed for Sinumerik 800-series configurations, this module is listed in Siemens catalogs and by third‑party distributors as a spare part to restore the graphics subsystem when the original board fails. As a dedicated graphics board, it handles the monochrome video output that drives the CNC’s display and associated interface elements, enabling operators to view program data and diagnostics on the control panel. The 6FX1126-1AA03 is commonly sought for service and maintenance of legacy Sinumerik systems, and is described in multiple distributor listings as a direct replacement part, compatible with appropriate Sinumerik hardware revisions. Typical applications include CNC retrofits, repair of failed graphics cards in Sinumerik installations, and ongoing service of Sinumerik 800-series machines in manufacturing environments that rely on visual CNC feedback. Procurers typically verify compatibility with their specific control revision and order this module as a spare to minimize downtime, ensuring continued access to the Sinumerik operator interface without replacing the entire controller.
