The FANUC A20B-3900-0162 is a memory board used in FANUC CNC control systems.

This memory module provides 16MB FROM and 3MB SRAM, supporting CNC system file storage, parameter handling, program data, and reliable controller operation.

The A20B-3900-0162 has been discontinued by the manufacturer, but tested replacement memory boards and repair support remain important for maintaining existing FANUC CNC equipment.

After replacement, related FROM files, CNC parameters, and programs may need to be reloaded according to the original machine configuration.

It is commonly used for CNC memory board replacement, SRAM/FROM module repair, system restoration, and machine tool maintenance when the original memory board becomes faulty, unstable, or unable to retain data correctly.
