Description
ORDERING NUMBER :- A02B-0207-J203
FANUC A20B-2002-0211 is a High-Speed Serial Bus (HSSB) Interface PCB used in FANUC CNC controller systems. It is part of the A20B-2002 series of control and interface boards.
🧠 Description
-
Part Number: A20B-2002-0211 (FANUC)
-
Type: HSSB Interface Printed Circuit Board (PCB)
-
Function: Acts as an interface board for the High-Speed Serial Bus (HSSB), facilitating fast digital communication between the CNC controller and peripheral modules or devices that use the HSSB protocol.
-
Series: Part of the A20B-2002 control board family used in FANUC CNC electronics.
⚙️ Role in CNC System
-
Communication Bridge: The HSSB interface board enables high-speed data transfer and synchronization between the main CNC controller and connected subsystems (e.g., operator panels, I/O cards, auxiliary modules).
-
CNC Integration: It is typically plugged into a backplane or connected via connectors to other PCBs, acting as the communication node for serial bus traffic within the control cabinet.
🛠 Typical Uses & Notes
-
-
-
This is not a power or CPU board but a communication interface board crucial for systems that use the HSSB protocol.
-
Boards like this are often sourced refurbished, surplus, or new from industrial electronics suppliers, and they may come with optional core exchange programs.
-
If you’re replacing one in the field, ensure your controller model supports HSSB communications and that the correct cables/connectors are in place.
