The FANUC A20B-2902-0500 is a high-capacity FROM/SRAM Memory Module (SMD Card) engineered for installation within FANUC CNC control backplanes, specifically supporting the FANUC Series 15-B, 16-C, 18-C, and 21-C frameworks. Built as a high-density, surface-mount device (SMD), this plug-in daughterboard provides 12 MB of Flash ROM (FROM) combined with 256 KB of Static RAM (SRAM). It acts as a dedicated, non-volatile data terminal, storing complex NC basis instruction sets, extensive PMC LADDER logic networks, and localized execution profiles. [stock available]
