Used in Fanuc Series 6A and 6B CNC machining centers and turning centers, the A20B-0008-0540 is a discrete I/O interface board designed to handle machine tool input and output signal routing within the control system. This board carries part number A20B-0008-0540 with revision /01A and board reference A350-0008-T544/01, both of which are visible on the PCB silkscreen. Manufactured by Fanuc in Japan, it is populated with standard TTL-family logic ICs including HD74LS174P devices and SN7406N buffers, consistent with the discrete I/O architecture used across the Fanuc 6 series control platform. Published specifications for this board indicate a capacity of 96 discrete inputs and 64 discrete outputs. The board fits the standard Fanuc 6 series card cage format and interfaces with the control backplane through edge connectors. It is a known direct replacement for the earlier A20B-0007-0040 board. The board is mounted in a gold-anodized aluminum carrier frame with standard card-cage slot hardware. Compatible controls include the Fanuc 6M and 6T series. Part number A20B-0008-0540 is the OEM market-recognized identifier used consistently in active US industrial surplus listings for this assembly.
