FANUCA20B-2200-0011Serial / DMA Add-On Option PCB for Series 15 CNC Control

Product Description

What this part is

A Fanuc A20B-2200-0011 printed circuit board — a plug-in serial / DMA add-on option card that mounts onto a Fanuc Series 15 CNC main board and adds serial communication and direct-memory-access transfer capability to the control. It is an option board that functions once seated in the host Series 15 control, and it is supplied as a bare card.

Decoding the order code

Fanuc part numbers are structured, and the field breakdown is what identifies whether a board will fit a given control.

A20B: Fanuc printed-circuit-board prefix. A20B covers sub-boards, add-on option cards and plug-in daughter boards; A16B is the prefix used for the larger multi-layer main and master boards.

2200: the control generation. The 2200 / 2201 group is the Fanuc Series 15 family (15A, 15B, 15M, 15T, 15P, 15G).

0011: the specific board within that generation, here the serial / DMA add-on function.

Suffix: a trailing /nnA style suffix seen on many Fanuc boards (for example /02A, /05C, /07E) is the board edition or revision level rather than a different part. Revisions are normally interchangeable within the same base number.

What these specs mean in practice

Because this is an option card tied to the Series 15 generation, the base number is the compatibility test. A20B-2200 boards seat in Series 15 hosts; Series 0, Series 16/18/21 and 160i/180i controls use different base groups (8100, 2900, 3300 and so on). The number is silk-screened on the existing board, along with the revision letter that some machine builders specify against firmware.

Quantity and configuration

Sold as 1 piece — one bare printed circuit board, new old stock in an opened box. The Series 15 main board or master card, card rack and backplane, CNC power supply, ribbon and serial cables, connector kits, memory modules and cartridges, backup battery, operator panel and MDI keyboard, and the control software and option-enable parameter are each separate items. Fanuc option boards generally also require a corresponding option parameter to be set in the control.

Interchange guidance

Searchable equivalents of the same part number: A20B-2200-0011, A20B22000011, A20B 2200 0011. Neighbouring numbers in the same group, such as A20B-2200-0012, are different functions on the same platform rather than interchanges.
