Description
📌 Description
The A20B‑2100‑0320 is a connector panel I/O expansion module (C) — a specialized printed circuit board used in FANUC CNC controllers and automation electronics to provide expanded input/output (I/O) capability beyond the basic connector panel interface. It allows additional signals to be routed between the CNC control’s internal electronics and external devices or wiring, helping expand system connectivity.
🧩 Function & Role
-
Acts as an I/O expansion module in the A20B‑2100 connector panel family, adding more I/O points or specialized signal pathways where needed.
-
Typically used in CNC control cabinets alongside other A20B‑2100 boards to extend the controller’s capability to interface with operator panels, sensors, switches, or other peripheral hardware.
-
The board is a PCB assembly designed for reliable signal transmission and integration within FANUC modular control systems.
📦 Applications
-
Industrial CNC machine tools (lathes, milling machines, machining centers) with FANUC controls
-
Automation equipment requiring expanded connector panel I/O beyond basic modules
-
Situations where additional electrical signal interfacing is needed in the control cabinet
🧠 Typical Characteristics
-
-
Connector panel expansion: Provides additional incoming/outgoing connection paths
-
PCB form factor: Designed to fit with other A20B‑2100 series boards
-
Integration: Works as part of a larger modular I/O and control system
