Description
A02B-0283-B803 – FANUC 3-Slot Stand-Alone Basic CNC Control Unit
The FANUC A02B-0283-B803 is a 3-slot basic CNC control chassis / backplane unit designed for industrial CNC systems. This is not a complete controller by itself — instead, it’s the core structural framework where control electronics are installed.
📌 Key Description
-
Part Number: A02B-0283-B803
-
Type: Stand-alone basic control unit / rack/backplane
-
Slot Configuration: 3 slots for inserting control boards such as CPU, I/O, display/interface modules.
🏭 Compatibility
-
Used primarily with FANUC Series 18i / 180i / 180i-SB CNC controllers, which are common control platforms for industrial machine tools (e.g., milling machines, lathes, machining centers).
⚙️ Function & Features
-
Base chassis/backplane: Serves as the structural and electrical backbone where compatible FANUC control PCBs are inserted.
-
Standalone design: Does not include the actual electronics — CPU boards, memory, I/O modules, or software must be added to make a working controller.
-
Fan-cooled: Built for reliable operation in industrial environments with internal cooling to help regulate temperature.
-
LED status indicator: Includes a basic status display (typically a single-digit 7-segment LED) for operational feedback.
-
Environmental ratings: Designed to operate in typical CNC cabinet environments (0 – 45 °C, vibration resistance, etc.).
📦 Typical Use Cases
-
Machine OEMs: Building custom CNC controller configurations.
-
Retrofit projects: Replacing worn or obsolete control chassis in existing equipment.
-
Service spares: Held as inventory by maintenance teams to reduce machine downtime.
