The FANUC A16B-3200-0320 is a Main CPU PCB and Master PCB used in compatible Series 16i/160i Model A stand-alone CNC control units.

FANUC CNC parts documentation identifies the A16B-3200-0320 as the 16i Main CPU Board, with hardware identification code E8. It is listed within the stand-alone control-unit structure covering the Series 16i and 160i platforms.

The board forms the central hardware platform onto which the required CPU, display-control, axis-control, memory, and other CNC modules are installed. Its actual machine-control capabilities depend on the cards, memory modules, software, options, and parameters fitted to the supplied board.

Organic product results commonly describe this model as:

• FANUC 16i/160i-A Main CPU PCB
• FANUC Series 16i Master PCB
• FANUC A16B-3200-0320 Main Board
• FANUC Stand-Alone CNC CPU Board
• FANUC CNC Control PCB.

The A16B-3200-0320 may be used to replace a confirmed faulty board associated with CNC startup failure, CPU or system alarms, intermittent control operation, failure to recognize installed cards, communication faults, or physical damage to the PCB.

• Main-board startup and communication functions tested before shipment
  
• In stock and prepared for prompt dispatch

FANUC’s parts table identifies the exact board as the Series 16i Main CPU Board and separately associates the stand-alone basic-unit structure with Series 16i/160i controls.

Stand-Alone Control Clarification

The term stand-alone describes the physical FANUC CNC control-unit architecture.

It does not mean that the A16B-3200-0320 can operate as an independent controller without the rest of the CNC hardware. A complete configuration may require:

• CPU card
• DRAM, SRAM, and FROM memory
• Axis-control card
• Display-control card
• CNC system software
• PMC ladder and parameters
• Servo and spindle software
• Communication or optional interface boards
• Compatible power supply and back panel

The final functions of the board therefore depend heavily on how it is populated and configured.

Similar Main CPU Boards

FANUC documentation distinguishes the following related Master PCBs:

• A16B-3200-0320: Series 16i Main CPU Board, ID E8
• A16B-3200-0325: Series 18i Main CPU Board, ID E9
• A16B-3200-0326: Series 21i Main CPU Board, ID EA.

Although these boards belong to the same hardware generation and may appear similar, they should not be treated as interchangeable.

A later FANUC parts listing also identifies A16B-3200-0420 as another Series 16i main CPU board. This is a separate, later hardware specification and is not an automatic substitute for A16B-3200-0320.
