FANUCA16B-2200-0800A16B-2200 Family CNC Control Board, Revision 10B — Series 16 / 18 / 21 Generation, Board Only

Product Description

What this part is

A Fanuc printed circuit board, part number A16B-2200-0800, revision /10B. It belongs to the A16B-2200 board family, which Fanuc used across the Series 16, 18 and 21 CNC generations.

What the part number tells you

A16B: Fanuc’s PCB prefix for older-generation control boards and drive units. The other prefixes in use are A17B and A20B.

2200: the board family. The A16B-2200 series is one of Fanuc’s most functionally diverse: it spans CNC main control, PMC, option expansion and robot axis boards. Documented members include A16B-2200-0900 (Series 16-A main CPU), A16B-2200-0910 (Series 16 Option 1 graphics), A16B-2200-0341 (PMC-M I/O Link ROM master) and A16B-2200-0854 (8-axis robot axis board for R-J). Family membership alone therefore tells you very little about the function of any one board in it.

0800: this specific board.

/10B: the revision. On Fanuc boards a revision change can mean a different memory capacity or a different feature set, not just a manufacturing tweak, so it is worth recording and matching.

How to identify the board you need

Fanuc PCBs carry a twelve-digit part number beginning with A, usually printed in yellow ink on the green board. A board marked with an A320 or A350 number carries the A16B/A17B/A20B number on the other side. Boards that mount to a master PCB or backplane often do not carry the full number in yellow at all; those have a yellow plastic frame with a mounting screw top and bottom, and a white barcode sticker on the top edge carrying the complete twelve-digit number.

Match the full number and the revision. A single digit’s difference in a Fanuc part number can mean a different memory capacity, and the machine’s software parameters are written against the hardware that was there.

Quantity and configuration

One board, new old stock, sold individually. The backplane or master PCB this mounts to, the rack and card cage, any daughter cards or memory modules, all cabling and mating connectors, the power supply unit, and any Fanuc system software, PMC ladder or machine data are each separate items.

Interchange guidance

Search forms include A16B-2200-0800, A16B22000800, A16B 2200 0800, A16B-2200-0800/10B, A16B-2200-0800-10B and A16B2200-0800. Related and adjacent A16B-2200 boards, listed for orientation rather than as substitutes: A16B-2200-0900 (Series 16-A main CPU), A16B-2200-0910 through -0919 (Series 16 option and graphics boards), A16B-2200-0341 (PMC-M I/O Link ROM master), A16B-2200-0854 (R-J robot axis board).

The Series 16 / 18 / 21 controls are legacy but still widely in production service, and Fanuc Corporation remains in business. Board-level repair and exchange for A16B boards is available from the legacy CNC trade — MRO Electric, FanucWorld and Radwell all handle this family.
