The FANUC part A20B-3900-0085 is an interface board with both SRAM and DRAM memory capabilities. This unit is specifically designed to enhance memory for various CNC programs and system firmware. Its specification includes a storage capacity of 256 MB, allowing for efficient handling of data and buffers in compatible FANUC systems. The device operates at a voltage of 3.3 volts and is equipped with two connectors to facilitate integration within existing systems.

Designed for compatibility, this board works seamlessly with the FANUC Series 16i-B, 18i-B, 21i-B, 0i-C, along with 30i, 31i, and 32i series models. The IP20 protection classification indicates that the board is suited for indoor use, shielding it against dust and foreign objects. Housed in a NEMA 1 enclosure, it can endure standard working environments.

The cooling mechanism is based on natural convection, which simplifies installation and reduces the need for additional cooling components. It maintains performance across a temperature spectrum, operating efficiently from 0 to 40 degrees Celsius. Moreover, the unit is designed to function in humidity levels not exceeding 80% (in a non-condensing state). When stored, it should be kept within the same humidity limits, ensuring preservation of its operational integrity. Furthermore, the board is rated for use at elevations up to 1000 meters above sea level, emphasizing its adaptability to various installation conditions.
