Fanuc A20B-3300-0020 Graphic Display Card

The FANUC A20B-3300-0020 Graphic Display Card is a CNC controller board module that performs graphic processing and display output for machine operator interfaces. Designed for FANUC Series 16i, 18i, and 21i controls, it drives the graphical interface on operator panels in machining centers, lathes, and automated manufacturing equipment. It mounts in the CNC controller PCB slot and communicates via the internal CNC system bus, with passive cooling to maintain reliability in industrial environments. This replacement card is used by maintenance teams, OEMs, and system integrators to restore CNC visualization and interface performance in FANUC CNC controls. Common replacements include A20B-3300-0010, A20B-3300-0030, and A20B-3300-0390.
