The Fanuc A20B-8100-0530 is a high-performance FL-NET (Factory LAN) interface printed circuit board designed for Fanuc Series 16i/18i/21i Model A CNC systems. This option board enables high-speed, deterministic Ethernet-based fieldbus communication for real-time data exchange between CNC controllers, PLCs, and factory automation devices. It features robust industrial-grade circuitry, dedicated FL-NET connectors (including CD38N), F-BUS backplane integration, and low-power operation on system-supplied voltages. [stock available]
