PRODUCT DESCRIPTION
FANUC A20B-3300-0104 - Main CPU Board
This FANUC A20B-3300-0104 is a critical Main CPU Board engineered for integration within FANUC CNC control systems. It functions as the central processing unit, responsible for executing machine programs, managing multi-axis control algorithms, and coordinating communication with peripheral modules. This component is fundamental for the operational integrity of industrial machine tools, including milling machines, lathes, and machining centers, typically utilizing FANUC 0i-MD or similar series controllers.
Technical Specifications:
- SERIES/FAMILY: FANUC 0i-MD Series, FANUC 16i/18i/21i-B Series (typical)
- COMPONENT TYPE: Main CPU Board / Control PCB
- ELECTRICAL SPECS: Operates on internal DC power supplied by the CNC system's power unit, typically 24VDC and 5VDC. Specific current draw is dependent on system load and configuration.
- MECHANICAL/PHYSICAL: Standard industrial PCB form factor, designed for slot or rack mounting within a FANUC control unit. Features multiple board-to-board connectors for internal bus communication and peripheral interfaces.
- INTERFACE/CONTROL: Utilizes FANUC's proprietary internal bus architecture for high-speed data exchange with servo amplifiers, I/O modules, and operator panels. Includes dedicated connectors for system integration and diagnostics.
- ENVIRONMENTAL/MOUNTING: Designed for operation within industrial control cabinets, typically requiring passive convection or forced air cooling within the enclosure. Operating temperature range is standard for industrial electronics, generally 0 to 55 degrees Celsius. Mounting via standard PCB standoffs or slot guides.
- COMPATIBILITY/APPLICATION: Directly compatible with FANUC 0i-MD, 16i/18i/21i-B series CNC controllers. Essential for machine tool applications requiring precise multi-axis motion control, program execution, and real-time data processing.
