FANUC A20B-1006-0110/03A Used Working Control Board

Product Overview

The Fanuc A20B-1006-0110/03A is a critical Master PCB (Printed Circuit Board) designed for the Fanuc Series 0-MC and 0-TC control systems. As a core processing component, this board manages the essential logic, axis communication, and system-wide coordination for CNC machining centers and lathes. The "/03A" designation indicates a specific hardware revision within the 1006-0110 family, typically used in 3-axis or 4-axis configurations. As a Used Working unit, this board is an indispensable resource for restoring legacy Fanuc controls to full operational status without the lead times or costs associated with new OEM replacements.

Key Features

• Main Logic Processing: Serves as the central "brain" for Fanuc 0M/0T Series C controls, executing G-code instructions and PLC ladder logic.
• Integrated Interface Slots: Features dedicated slots for additional plug-in modules, including fiber optic I/O boards, additional axis control cards, and memory expansion.
• Bus Communication: Facilitates high-speed data transfer between the CPU and peripheral units, ensuring synchronized movement and real-time feedback.
• High-Reliability Components: Built with industrial-grade surface-mount components designed for the high-vibration and thermal-cycling environments of machine shops.
• Comprehensive Diagnostic LEDs: Includes onboard status indicators to assist technicians in identifying power supply health, watchdog timer status, and system faults.
• Legendary Fanuc Durability: Engineered for 24/7 industrial duty cycles, maintaining precise timing and signal integrity over decades of service.

Item Condition (Used Working)

• Functional Status: Used Working. This board has been professionally pulled from a functional Fanuc 0-Series control rack. It has passed "Power-On Self-Test" (POST) and basic I/O communication checks.
• Physical State: Clean industrial condition. The multi-pin edge connectors and socketed chips are in excellent shape. No evidence of "burnt" traces or repair soldering was found during visual inspection.
• Technical Integrity: All surface-mount capacitors and logic ICs appear to be in good health. The board has been stored in an antistatic (ESD) environment to prevent electrostatic damage.
• Note: Professional installation by a Fanuc-certified technician is required. Please ensure that you transfer your specific system parameters and EPROM/SRAM data from your original board, as this unit is provided with standard factory settings.
