FANUC A20B‑2100‑0782 — Description
🔹 Part Number: A20B‑2100‑0782
🔹 Product Family: FANUC A20B‑2100 series (internal control/display PCBs for FANUC CNC controller systems)
🔹 Component Type: PANEL i TERMINAL INTERFACE MAIN CPU PCB
📋 Description:
The A20B‑2100‑0782 is an internal printed circuit board (PCB) used within FANUC CNC controller operator panels. It functions as the main CPU/interface board for the PANEL i terminal, handling core communication and control tasks between the operator panel display, keypad inputs, and the main CNC control logic. This board is part of the A20B‑2100 series, which includes control and interface PCBs for various display sizes and operating environments.
🔌 Typical Role & Functionality:
-
Acts as the central interface PCB for a 15.0‑inch (or similar size) LCD display assembly in FANUC operator panels.
-
Facilitates communication between the operator panel hardware (display, keys, touchscreen if present) and the CNC controller’s main processing system.
-
Supports menu display, status feedback, and interaction functions — essentially the “brains” of the PANEL i display unit.
📦 Usage Context:
This board is typically mounted inside the CNC controller’s operator console rather than being a standalone display. It works together with the LCD screen, touch/mode buttons, and peripheral interface boards to provide a seamless operator interface. Because it’s a core PCB, replacement usually requires a core exchange with the vendor.
