Physical Characteristics and Installation

This memory circuit board weighs approximately 0.48 kg for secure rack mounting. Its dimensions measure 220 mm x 180 mm x 25 mm for CNC controller cabinets. First, align the A16B-2201-0101/06A with the backplane guides. Then, press firmly until the board seats completely. Finally, secure the board using the top and bottom retaining screws. A conformal coating protects the PCB from moisture and dust.

Memory Specifications and Backup

The A16B-2201-0101/06A integrates 256 KB of CMOS RAM for part program storage. Data memory provides 64 KB for CNC parameters, tool offsets, and work coordinates. A replaceable lithium battery maintains all memory during power-down periods. The battery life reaches 5 years under normal conditions. Consequently, your programs remain safe for extended machine shutdowns. You can expand the memory up to 1 MB using optional modules.

Component Layout and Compatibility

This memory board contains 12 integrated circuits for memory management and addressing. Thirty capacitors provide power filtering and noise suppression. Twenty-five resistors establish proper signal levels and termination. The A16B-2201-0101/06A works with various GE Fanuc CNC controllers including Series 0, 15, 16, and 18. Use this board for storing large part programs and custom macros.
