This non-volatile EEPROM memory module uses NEC uPD28C64-250 memory and is intended to retain the controller’s essential memory content when power is removed. As a component in the 1747 memory module family, the M1 occupies a dedicated slot in the SLC 500 chassis and sits alongside higher-capacity options such as the M2 (4K) and M13 (64K) modules in later configurations. Common applications include saving configuration data and program elements for SLC 5\/01\/5\/02 systems in legacy automation projects, enabling straightforward data migration or recovery in the event of processor or power interruptions.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658956833070,"sku":null,"price":4205.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_777bad86-a119-45c9-a5b9-b45fdd60d638.jpg?v=1769525951","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-m1-memory-module","provider":"PLG Automation ","version":"1.0","type":"link"}
