Description
📌 FANUC A16B‑3200‑0500 — ZERO iB I/O PCB (Without Data Server)
Description:
The FANUC A16B‑3200‑0500 is an input/output (I/O) printed circuit board used in the ZERO iB (0i‑B) family of FANUC CNC controllers. It functions as a core I/O interface board that connects the controller’s internal logic to external machine signals (such as sensors, switches, relays, and actuators), enabling the CNC to monitor and control machine functions.
Key Functions & Features:
-
🔌 I/O Interface Board: Handles the digital and analog input/output signals between the CNC control system and machine peripherals. This includes reading sensor statuses and driving outputs used for machine control.
-
📍 ZERO iB Compatibility: Designed specifically for FANUC ZERO iB (0i‑B / 0i‑TB) controllers, typically used with the A16B‑3200‑0491 CPU board as part of the controller’s core electronics.
-
🧱 No Data Server: This version does not include a data server function — meaning it focuses purely on basic I/O processing, unlike the related A16B‑3200‑0501 which includes a data server capability.
-
⚙️ Industrial Use: Integral to machine operation logic — ensuring commands from the CNC’s PMC and CPU translate correctly into physical actions on the machine.
-
🔄 Modular PCB: This board is part of FANUC’s modular control architecture and is installed on the controller backplane or mounted inside the control cabinet.
Typical Applications:
-
Found in FANUC 0i‑B / ZERO iB CNC systems (e.g., 0i‑TB, similar configurations) where it serves as the main I/O interface for the controller.
-
Works with machine limit switches, coolant controls, spindle enables, tool change signals, and other digital/analog machine signals.
