Description
📌 FANUC A20B-3300-0361 — Display Control Module
A20B-3300-0361 is a display control module (a printed circuit board) used in FANUC CNC controller systems to manage the machine’s visual interface and display functions.
🖥️ What It Does
-
Display Control Module: This board handles the communication between the CNC controller’s main processor and the operator display panel — ensuring that menus, status information, and graphical/text output show correctly on the screen.
-
Part of the A20B-3300 Series: It belongs to the A20B-3300 family of FANUC PCBs that are typically installed inside CNC control cabinets.
-
Role in CNC Systems: Without a functioning display control module like this, the CNC controller might still run, but the operator interface may not work properly or may not show any information.
📋 Typical Context
-
Used in various FANUC CNC controller models where an external display (CRT or LCD) needs to be driven by the controller electronics.
-
Often sourced new, refurbished, or surplus from industrial parts suppliers — usually tested before installation.
