A20B-2901-0480 Fanuc Graphic Control Module

The A20B-2901-0480 is a Fanuc graphic control module used in Series 15 CNC systems where stable CRT display output and reliable screen-side control are important for daily machine operation. Identified as a CRT board, this module supports the display-related functions that allow operators to view machine information, alarms, programs, parameters, and status data clearly.

Because this model has been discontinued by the manufacturer, it is now mainly requested by customers maintaining older Fanuc Series 15 equipment, replacing faulty CRT display boards, or preparing spare stock for long-term support. In real maintenance work, the A20B 2901 0480 remains important because display-side faults can make a machine difficult to use even when the core CNC control is still functional.

At REACO CNC, we supply dependable Fanuc parts for customers who need replacement graphic control modules, CRT boards, backup stock, or Fanuc repair support for installed CNC systems.

The A20B-2901-0480 Fanuc CRT board is especially relevant in legacy Series 15 controls where the original display structure must be preserved. Unlike a general control PCB, this board is more closely tied to screen output and graphic control. When the CRT board becomes unstable, operators may experience display loss, weak screen output, graphic display problems, flickering, or other interface issues that slow down both operation and troubleshooting.

For many maintenance teams, replacing the correct A20B-2901-0480 is often the most practical way to restore display usability without changing the wider control system.

This board is commonly associated with:

• Fanuc Series 15 CNC systems
• CRT display control applications
• Graphic control and screen output support
• Legacy CNC display maintenance
• Service work requiring original-compatible Fanuc control PCBs

It may also be sourced together with related CRT modules, graphic control boards, display boards, operator panel PCBs, main control boards, Fanuc controller parts, servo amplifier units, spindle drive units, and other CNC electronic assemblies during broader repair work.

Depending on stock availability, this board may be supplied in:

• New condition
• Refurbished condition
• Used condition

For discontinued CRT-related boards, refurbished stock is often a practical choice. It helps customers keep older Series 15 CNC systems running while controlling repair cost and lead time.

Customers usually look for the A20B-2901-0480 when they need:

• A direct replacement for a faulty Series 15 CRT board
• Support for discontinued Fanuc graphic control hardware
• Reliable Fanuc stock for legacy CNC systems
• Access to dependable Fanuc parts for display-related repair
• Help deciding between replacement and Fanuc repair

In real production environments, display problems can slow down service work quickly because the operator screen is needed for alarms, diagnostics, parameters, and machine status. Having the correct A20B-2901-0480 available can help restore normal screen function and reduce unnecessary downtime.

REACO CNC supports both direct replacement supply and Fanuc repair inquiries. If your original A20B-2901-0480 is damaged, we can help review whether repair is practical or whether replacement is the better option based on stock, condition, and urgency.

We also support sourcing for related Fanuc parts, including CRT boards, graphic control modules, display PCBs, operator panel boards, main control PCBs, servo amplifier modules, spindle drive units, and other CNC electronic assemblies used in installed Fanuc systems.

For many factories, older Fanuc Series 15 machines are still useful production assets. A correct A20B 2901 0480 replacement can help restore display stability, preserve the original control structure, and avoid unnecessary system changes when the machine is still worth maintaining.
