Description
xFANUC A16B‑2201‑0110 is a printed circuit board (PCB) used in industrial FANUC CNC controller systems, serving as an I/O interface card that handles digital input and output signals between the controller logic and the machine’s I/O hardware.
🧠 What It Does
-
Part Number: A16B‑2201‑0110
-
Category: I/O Interface Board (Digital I/O PCB)
-
Function: Interfaces digital input and output signals between the CNC controller’s core control circuitry and external devices — such as sensors, limit switches, emergency stops, spindle on/off, coolant, and other machine signals.
-
Series: Part of the FANUC A16B‑2201 series of I/O PCBs, commonly used in older FANUC CNC controllers (e.g., Series 16, Series 18).
📋 Role in a FANUC Controller
This board plays a key role in handling discrete (on/off) signal communication for the controller:
-
🟢 Inputs: Accepts signals from machine devices like limit switches, door sensors, feed hold, cycle start, etc.
-
🔵 Outputs: Sends signals to relays, spindle control circuits, alarm indicators, and other outputs that control machine actuators.
-
🔄 Communicates with the main control logic via the controller’s internal bus or I/O link architecture.
It essentially acts as a bridge between the CNC controller and the machine’s electrical/field hardware, making sure commands from the CNC logic reach the machine (outputs) and status/condition signals from the machine reach the controller (inputs).
⚙️ Typical Usage
-
Used in older/modular FANUC CNC controllers (before A20B family became widespread), especially where multiple discrete I/O points are required.
-
Commonly found in:
-
Machine tool controllers
-
Machining centers
-
Lathes and turning centers
-
Legacy or retrofitted CNC installations
