A20B-8201-0541 Fanuc 24VDC 30i/31i/32i Series CNC Control Board

Description

Fanuc A20B-8201-0541 is a high-performance CNC control board featuring a 200 mm x 150 mm multi-layer PCB architecture designed for 24 VDC nominal operation within the 30i, 31i, and 32i series systems. The hardware incorporates high-density surface-mount components, integrated HSSB (High-Speed Serial Bus) communication interfaces, and fiber-optic port connectivity for low-latency data transmission. The board utilizes a rigid FR-4 substrate with gold-plated contact points to ensure signal integrity across complex logic circuits and high-speed processing units.
