FANUC A20B-2902-0191 Product Overview
The FANUC A20B-2902-0191 is a plug-in PMC DRAM module configured with 2MB of application DRAM and 512KB of management expansion RAM. It is used in compatible legacy FANUC CNC option-board configurations to provide working memory for supported PMC functions.
FANUC maintenance documentation lists the A20B-2902-0191 within the A20B-2902-019x PMC DRAM family. The exact -0191 suffix is important because other modules in this family have different manager and application memory combinations.
Verified Memory Configuration
- Module Type: PMC DRAM module
- Application DRAM: 2MB
- Management Expansion RAM: 512KB
- Installation: Compatible PMC option-board configuration
- Memory Type: Volatile working memory
This module is not a substitute for a CNC SRAM or FROM module used for retained machine data or system software. Its role is to provide working DRAM for the configured PMC management and application environment.
0191 Model Clarification
The A20B-2902-0191 combines 512KB of manager expansion RAM with 2MB of application DRAM. It should not be confused with the A20B-2902-0196, which provides 2MB of application DRAM without the same manager-memory configuration. Similar appearance does not confirm interchangeability.
Compatibility and Replacement Check
Before ordering, verify the complete A20B-2902-0191 number, printed revision, host option-board number, PMC type, socket location and original system configuration. Compare photographs of the component layout and connector contacts where possible.
Power must be removed before installation, and the module should be handled using appropriate ESD precautions. Back up available CNC and PMC data before servicing the control, even though this DRAM module itself is used as volatile working memory.
