Information About A20B-3900-0224
The A20B-3900-0224 is part of the FANUC A20B-3900 series, designed to extend memory capabilities within FANUC automation controllers. Specifically compatible with the R-30iA controller main boards A16B-3200-0600 and A16B-3200-0601, it installs horizontally for seamless integration. Featuring 32MB of FROM (Flash ROM) for program storage and 2MB of SRAM for high-speed access, this module improves performance and reliability. Although discontinued by the manufacturer, it remains widely used in industrial automation systems where FANUC controllers are deployed.
Key Features:
- Controller Compatibility: Designed for FANUC R-J3iC and R-30iA controllers.
- Memory Expansion: Provides 32MB FROM for storage and 2MB SRAM for rapid processing.
- Installation Method: Mounts horizontally onto supported controller boards.
- Supported Main Boards: Compatible with A16B-3200-0600 (standard) and A16B-3200-0601 (force sensor option).
- Discontinued Product: No longer manufactured, but available in surplus condition.
- Reload Requirement: All FROM files, parameters, and programs must be reloaded after installation.
- Lightweight Design: Weighs just 0.04 lbs, minimizing impact on system form factor.
- Industrial Reliability: Built to FANUC standards for long-term CNC and robotics applications.
The A20B-3900-0224 delivers the reliability and memory performance required for advanced CNC controllers and robotic systems.
