The Fanuc A16B-1310-0310 is a specialized FAPT memory printed circuit board designed for Fanuc Series 11 (11F) CNC systems. This plug-in module provides expanded memory capacity for FAPT (Fanuc Automatic Programming Tool) functions, including part program storage, custom macro data, and conversational programming support. It features industrial-grade memory chips (often with battery backup for data retention), robust edge connectors for direct integration with the main control board, and low-power CMOS circuitry operating on system-supplied voltages.
