📦 A20B‑2101‑0071 — Description
Part Number: A20B‑2101‑0071
Description: FANUC Printed Circuit Board (PCB) – Control Board used in CNC control electronics and automation systems.
📌 What It Is
The FANUC A20B‑2101‑0071 is an internal printed circuit board (PCB) used within FANUC CNC controller and automation electronics. It belongs to the A20B‑2101 series of internal controller boards that perform logic, control, and signal routing functions critical for machine automation.
📌 These boards are not external interfaces or operator panels — they operate inside the controller cabinet or drive assembly and form part of the CNC logic and control infrastructure.
🧠 Typical Function & Role
- ✔ Acts as a control board (PCB) inside the CNC controller or automation electronics.
- ✔ Handles internal logic, signal routing, and control processing between other PCBs (CPU boards, I/O racks, interface modules).
- ✔ Installed on the machine’s control backplane or PCB rack.
📍 The A20B‑2101 prefix typically denotes boards linked with FANUC’s control logic and system boards (as opposed to high‑power output modules like servo drives).
⚙️ Where It’s Used
- Inside FANUC CNC machine controllers
- Part of the internal electronics ensuring proper coordination and communication
- Not a standalone component — works with other FANUC boards in the control system
📌 Summary
👉 A20B‑2101‑0071 is a FANUC internal control PCB used in CNC controller electronics.
👉 It supports control logic, signal routing, and system communication within the FANUC control cabinet.
👉 It’s an essential internal component rather than an external user interface or power module.
