A20B-2902-0080
FANUC A20B-2902-0080 combined memory module. This 4MB flash rom with 512K static random access memory. With 4MB of FROM allowing a lower sized ladder libraries and NC basis instruction sets. The 512K SRAM is for smaller controls allowing the CPU processor on the main or seperate processor to pull from the FROM using the SRAM and DRAM memories.
At DNC we try to keep an active stock of boards such as this A20B29020080. Contact us for more information. Don’t forget we also repair the complete controls that boards such as this are fitted too. As a rule certainly for testing any of the SMD’s, main peripheral PCB’s, main pcb or the PSU; then we prefer to test the entire system. For fault information on the Fanuc 16/18/21 controls, please check our fault / alarms and error codes pages.
