FANUCHigh-Speed Base 2 Backplane Board for Series 15 / 15B CNC, Additional-Memory Configuration, Rev 03A

Product Description

What this part is

A Fanuc A16B-2200-0741, the high-speed Base 2 board for the Fanuc Series 15 / 15B CNC family, in the configuration carrying the additional memory used on 15 and 150 controls. In the Series 15 architecture the base board is the motherboard of the control: it carries the bus that the CPU, axis, memory, graphic and I/O option cards plug into, distributes internal power and routes the inter-card signals. Repair houses list it as the HI-SPEED BASE 2 PCB. It is the base and backplane board of the control, not a processor, axis or I/O card. A fault in a specific function such as an axis, a screen or a comms port usually lies in a card that plugs into this board.

Decoding the order code

A16B is the Fanuc printed-circuit-board product class, Fanuc’s own numbering rather than the GE Fanuc IC-series scheme. 2200 is the board family block. 0741 is the high-speed Base 2 board specification, additional-memory configuration for Series 15 and 150 control. The /03A suffix is the hardware revision stamped on this board; revisions of the same base number are the same board specification.

Published specifications

Type: CNC base board and backplane, Base 2, high-speed version. Configuration: high-speed Base 2 with additional memory, 15 / 150 control. Host controls: Fanuc Series 15, 15A and 15B CNC. Function: card-bus backplane, internal signal routing and power distribution for the CNC card set. Board revision on this unit: 03A. Origin: Japan (Fanuc nameplate).

What these specs mean in practice

Base boards are configuration-specific. The high-speed Base 2 variant supports the faster Series 15 CPU and the larger memory fit, and a standard-speed or different-slot base is not a substitute even where the physical envelope looks the same. The base board defines the slot map, so a replacement accepts the same card set the machine already carries.

Mounting data

Plug-in cards occupy the same slot positions on the replacement base as on the original. The Series 15 control keeps its parameters and part programs in battery-backed SRAM on the memory card. The board is static-sensitive.

What is not included

Board only. No CPU, axis, memory, graphic or I/O cards, no card cage, rack or CNC cabinet, no power supply unit, no operator panel or CRT/LCD, no battery, no cables, connector kits or terminal boards, no software and no documentation.

Quantity and configuration

Sold as one board.

Interchange guidance

A16B-2200-0741, A16B22000741 and A16B-2200-0741/03A are the same part number with a revision suffix. Other A16B-2200 numbers are different boards: -0141, -0020 and -0220 are not substitutes for a Base 2 board. Fanuc and GE Fanuc branded examples of this number are the same board.
