FANUCMain CPU / Master Control Board for Series 16 / 18 CNC Control

Product Description

What this part is

A Fanuc A16B-2200-0500 main CPU board — the master card of a Series 16 / Series 18 generation CNC control. On this generation the master board is the spine of the control: the CNC processor and its bus live here, and the peripheral cards and SMD plug-in modules that give the control its axis count, memory size, graphics and I/O capability all mount onto it. It is a CPU / master-tier board, supplied as a bare board.

Decoding the order code

A16B: Fanuc printed-circuit-board prefix for the large multi-layer main, master, axis and servo boards. A20B is the prefix for the smaller sub-boards and plug-in daughter cards.

2200: the control generation group. A16B-2200 boards belong to the Fanuc Series 15 / 16 / 18 generation; the sibling A16B-2200-0900 is documented as the main CPU board of the Series 16-A.

0500: the specific board within that generation.

The base number A16B-2200-0500 is the ordering and matching number.

What these specs mean in practice

Two boards with the same A16B-2200 base number can behave differently depending on which SMD modules are plugged into them — that is how Fanuc configured axis count, memory and options on this generation. The base number governs fit; the fitted modules govern capability. The full number silk-screened on the board, together with any edition suffix after the slash, is the authoritative identifier, and the module-to-socket layout is part of the configuration.

A16B-2200 boards seat in Series 15 / 16 / 18 generation controls. Series 0 controls and the later i-series controls use different base groups such as 1000, 8100 and 3300.

Quantity and configuration

Sold as 1 piece — one bare main CPU board. New old stock, in an opened box. CNC system software, parameters, PMC ladder and the SMD plug-in modules come from the receiving control.

Interchange guidance

Searchable equivalents of the same part: A16B-2200-0500, A16B22000500, A16B 2200 0500, A16B-2200-0500-R, A16B22000500R. Different editions of the same base number are the same board at a different revision level. Adjacent numbers such as A16B-2200-0092 or A16B-2200-0900 are different boards on the same platform — related, not interchangeable.
