It plugs into the 1756 backplane and works in concert with 1756-L55 family controllers to extend the memory available for ladder logic, structured text, and data tables, enabling larger arrays, more extensive data logging, and more sophisticated control decisions in complex automation tasks. The M14 is part of the 1756 memory expansion lineup and is documented in official installation and configuration guides for ControlLogix memory boards, which describe how to add the module to an existing rack and how the expansion memory is addressed by the controller. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658925506862,"sku":null,"price":44.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b50a44ee-cbd5-4884-bc68-ed54b6e1fabc.jpg?v=1769525650","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-m14-memory-expansion-module","provider":"PLG Automation ","version":"1.0","type":"link"}
