Description
📌 FANUC A20B-3300-0362 — Display/MDI Control Module
The FANUC A20B-3300-0362 is a display control module used in FANUC CNC controllers. It’s part of the A20B-3300 series of printed circuit boards (PCBs) that handle display and operator interface functions inside the CNC control system.
🧠 What It Does
-
🖥️ Display/MDI Control Module: This board is responsible for driving the display output (graphics or text) and handling manual data input (MDI) interface signals in the CNC controller.
-
📊 Operator Interface: It links the CNC’s processor and the operator panel, ensuring that menus, coordinates, program info, and other interface elements show correctly on the screen.
-
🌐 Embedded Ethernet (in some variants): Some versions of this module support embedded Ethernet connectivity for network communication in FANUC i-Series controls.
📋 Typical Use
This module is used in FANUC CNC systems — especially i-Series (like 16i, 18i, or 21i), including “B” and “S-B” models — to control the communication between the machine’s display panel and the main controller electronics.
