PRODUCT DESCRIPTION
FANUC A20B-2902-0412 - I/O Link-i Interface Board
This component is a critical Printed Circuit Board (PCB) from the FANUC A20B-2902 series, engineered for integration within FANUC 0i-MD, 16i/18i/21i-B series CNC control systems. It functions as an I/O Link-i interface, facilitating high-speed serial communication between the main CNC processor and distributed I/O modules, servo amplifiers, and other peripheral devices. This board is essential for robust, integrated control in machine tools, industrial robots, and automated manufacturing applications.
