Description
Description:
The A20B‑2100‑0781 is an internal printed circuit board (PCB) used within FANUC CNC control systems — specifically functioning as a main interface PCB for the operator panel / CPU display module, often associated with a 12.1‑inch LCD display assembly or similar operator panel electronics. It connects and interfaces the display and controls to the main controller logic, acting as a core part of the PANEL i terminal interface / main CPU circuitry.
📌 Key Points:
-
🧠 Panel Interface Main CPU PCB: This board handles operator panel interface and connects to the main CNC controller.
-
🖥️ Often associated with displays around 12.1″ LCD size in FANUC operator panels (depending on exact controller configuration).
-
⚙️ Part of the A20B‑2100 series, a group of PCBs that provide control logic, interface, and communication functions inside FANUC CNC electronics.
-
🔁 Typically refurbished or supplied as spare, and can require a core exchange through parts suppliers.
📦 Typical Use:
This board is normally mounted inside the CNC controller or operator console, linking display hardware (LCD and keypad) with the controller’s CPU and backplane. It plays a critical role in rendering the user interface and communication between the operator panel and main control logic.
In short:
The A20B‑2100‑0781 is a main CPU/interface PCB for FANUC operator panel displays, serving as a central electronic board that supports and connects the panel’s display and user interface to the underlying CNC control system.
