It provides permanent storage for user programs and processor data, protecting control logic against data loss caused by battery failure or prolonged power outages. Designed to plug directly into compatible SLC 500 processors, the \u003cstrong\u003e1747-M12\u003c\/strong\u003e ensures fast program recovery and reliable system restores in industrial automation environments.\u003c\/p\u003e\n\u003ch3\u003eMemory Capacity and Technology\u003c\/h3\u003e\n\u003cp\u003eFeaturing 64 KB of EPROM (Erasable Programmable Read-Only Memory) storage capacity, the module retains user ladder logic programs and system configuration settings without requiring continuous backplane or battery power. It is ideal for safeguarding critical PLC applications and serving as a master backup image for rapid controller restoration.\u003c\/p\u003e\n\u003ch3\u003eHardware Installation and Compatibility\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1747-M12\u003c\/strong\u003e installs directly into the dedicated memory module socket located on compatible SLC 500 CPU boards, including select SLC 5\/01, 5\/02, 5\/03, 5\/04, and 5\/05 controllers. Once installed, processor operating modes can be configured via programming software (such as RSLogix 500) to automatically load the EPROM contents into processor RAM upon power-up or memory corruption detection.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1747-M12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eMemory Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Platform\u003c\/td\u003e\n\u003ctd\u003eSLC 500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory Type\u003c\/td\u003e\n\u003ctd\u003eEPROM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory Size\u003c\/td\u003e\n\u003ctd\u003e64K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.05 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1747-M12 memory module require battery power to retain data? A: No, as an EPROM device, the 1747-M12 provides non-volatile storage and retains user programs and data without requiring a battery.\u003c\/p\u003e\n\u003cp\u003eQ: How does the SLC processor utilize the 1747-M12 memory module during operation? A: Depending on controller configuration settings in RSLogix 500, the processor can automatically transfer stored ladder logic from the 1747-M12 into internal RAM upon system initialization or power-up.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":67167118950515,"sku":"1747-M12","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1747-M122_Cocoai_5e883b03-70fb-44fa-bffc-555120c7e04a.jpg?v=1794380745","url":"https:\/\/www.dcssupplier.com\/ar\/products\/allen-bradley-1747-m12-slc-500-eprom-memory-module","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
