Design and Performance
High-Density 48/32 I/O for Complex Operator Panel Interfacing
With 48 digital inputs and 32 digital outputs, the A20B-2002-0521 provides extensive connectivity for operator panel switches, indicator lamps, and machine interface signals within a single compact I/O board.
Reliable FANUC I/O Link Communication
Communicating with the CNC system through the established FANUC I/O Link protocol, this board ensures compatible, low-latency data exchange between the operator panel and connected FANUC control systems.
Streamlined Design Without MPG Interface
Less populated than the related A20B-2002-0520 variant, this board omits the manual pulse generator (MPG) connector, making it the correct choice for operator panel configurations that do not require manual pulse-based jogging control.
Broad Compatibility Across Multiple FANUC CNC Generations
Fitted on many different configurations of lathes, machining centers, and other CNC machine tools, this board supports a wide range of FANUC i-series control systems (0i through 21i), simplifying sourcing across diverse machine tool installations.
Robust IP54 Protection for Panel-Mounted Reliability
Rated IP54 for dust and water resistance, this board supports reliable long-term operation when panel-mounted in typical industrial CNC operator station environments.
