The A20B-2900-0553 memory module from FANUC is characterized by its dynamic random access memory (DRAM) technology. This module provides a memory capacity totaling 128 kilobytes. It is compatible with Model B CPU main boards from the Series 15, 16, and 150, making it versatile for various applications within these series.

An LED indicator on the module is included to alert users to the status of the memory, indicating whether it is present or if an error has occurred. The module functions effectively in ambient temperatures ranging from 0 °C to 45°C while operating in a non-condensing environment. For storage, the module may be kept at temperatures between -20 and 60°C under the same non-condensing conditions.

This module resists vibrations up to 0.5G, which can be beneficial in environments where equipment might experience some movement. It is designed for slot mounting, ensuring straightforward installation in compatible devices. Additionally, a lithium battery serves as a backup for the memory, providing reliability in retaining data in the event of power loss.
