A20B-2902-0412
FANUC A20B-2902-0412 memory board. Is a unique combination of two different types of memory FROM and SRAM (static random access memory). Between the two different memory systems; allowing the Fanuc Series 16-TT control to compute faster. The FROM is 4MB and the SRAM is 256KB; while on the lower end of capacity even for Fanuc it was still a very novel approach combining the two into one PCB across one bus port. No doubt this board and variations of RAM/ROM capacity were fitted into other Fanuc control systems.
At DNC we try to keep an active stock of boards such as this A20B29020412. 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.
