The 1756-M1 memory module provides 512 KB of expansion memory for 1756-L1 family CPUs, enabling larger programs and data storage in a single rack. This processor is part of the older ControlLogix line and was discontinued in 2009, making it a candidate mainly for legacy systems or training setups. In a typical installation, the L1 serves as the central processor in a ControlLogix chassis, coordinating I\/O through compatible modules and a power supply to form a complete automation rack.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657301295406,"sku":null,"price":171.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d1b63d4f-ecc7-4936-a492-1b0ceb1c61e5.jpg?v=1769467683","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-l1-controllogix-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
