🧠 What A17B-3300-0400 Is
-
Part Number: A17B-3300-0400
-
Description: High-speed RISC PCB CPU module — a printed circuit board that functions as a CPU/control card handling processing tasks in the controller.
-
Product Series: Part of the A17B-3300 series of FANUC industrial control PCBs.
-
Role: Acts as a CPU module responsible for executing core logic and control functions inside a FANUC CNC controller or related machine control system — similar in concept to the CPU card in computer-based controllers.
🔧 Typical Use & Context
-
Integrated into the control electronics rack of FANUC-based systems where processing power is needed for real-time control, motion logic, and system coordination.
-
Found alongside other boards such as axis modules, I/O cards, memory boards, and power supplies inside CNC or automation controller cabinets.
-
Dimensions, power, and specific connection headers depend on the exact controller frame and backplane it is designed to fit.
-
New or refurbished modules may be supplied by third-party vendors; services like repair, reconditioning, and testing are often offered.
⚙️ Notes
-
The successor part according to some listings is A17B-3300-0402, indicating variations or revisions in the module series.
-
Because it’s a CPU module used in industrial equipment, replacing or installing this board typically requires careful handling of configuration data and backups to preserve machine parameters.
