{"product_id":"siemens-6es7953-8lj20-0aa0-programmable-logic-controller-module","title":"Siemens 6ES7953-8LJ20-0AA0 Programmable Logic Controller Module","description":"\u003cdiv\u003e\u003cp\u003eSiemens 6ES7953-8LJ20-0AA0 is a SIMATIC Micro Memory Card P designed for S7-300 family deployments, including S7-300\/C7 and ET 200 I\/O subsystems. This 3.3 V non-volatile NFLash memory module provides 512 KB of storage capacity, intended to hold program and configuration data for compatible Siemens controllers. Sold as a spare part, it supports replacement in legacy installations where memory-card-based storage is required to preserve system settings and project data. The component is part of Siemens' Micro Memory Card P lineup and is specifically described as a 512 KB NFLash card for S7-300\/C7\/ET 200 devices. Siemens lists this part as End of Life, with the product no longer available since October 1, 2021, and points to a successor model 6ES7953-8LJ31-0AA0. In practice, users retrofit these cards within older S7-300 setups to restore memory functionality without rewriting controller programs, though availability from official channels has diminished. For purchasers evaluating compatibility, confirm that the target device supports Micro Memory Card P modules from the 6ES7953 series and note the recommended migration path to the indicated successor when planning a replacement.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New Surplus No Box","offer_id":46268598092010,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6es7953-8lj20-0aa0-programmable-logic-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
