The Fanuc A20B-0008-0280 is a specialized Tape Reader RS-232C Interface PCB designed for Fanuc Series 6, 10, 11, and 15 CNC systems. This chassis-mount board enables reliable bidirectional data transfer between external tape readers/punchers and the CNC control via RS-232C serial communication (with optional 20mA current loop support in related configurations). It features industrial-grade logic circuitry, robust connectors for direct integration with the main CPU or MDI/CRT unit, and low-power operation on system-supplied voltages. [stock available]
