The ASE908131 stores program code and process data inside Schneider’s Modicon automation platform. This module measures roughly 6.5 inches long, 1.0 inch wide, and 4.0 inches high. Moreover, it weighs about 0.4 pounds, so cabinet space stays efficient. Engineers add the ASE908131 when controllers need extra memory for larger applications.
Technical Specifications and Interface Details
The unit expands onboard memory capacity and therefore supports complex control programs. Specifically, it provides non-volatile storage that retains data without continuous power. Additionally, a keyed edge connector links the module directly to the host processor board. The compact housing fits standard Modicon card slots.

Energy Storage and Data Retention
An onboard battery on the ASE908131 preserves stored program code during power interruptions. Consequently, the controller restarts without reloading applications from external media. Internal capacitors further stabilize logic voltage across brief supply dips. This buffering therefore protects critical configuration data in continuous processes.
Installation and Compatibility Notes
Because the ASE908131 slides into standard Modicon slots, technicians complete installation quickly. They should confirm connector alignment before they apply power to the system. Furthermore, the module integrates smoothly with existing Modicon processors and racks. Always store spare units in anti-static packaging to protect sensitive circuitry.
