It provides 2 MB of user memory and 478 KB of I\/O memory, with optional nonvolatile storage via a CompactFlash card to preserve data between power cycles. This CPU is designed for use within the ControlLogix 5561 family and installs into a 1756 backplane, enabling scalable control of sequential, process, and motion-related applications when paired with appropriate I\/O and networking modules. Typical electrical characteristics include a backplane current of about 1.20 A at 5 V and a power dissipation around 3.5 W, with a weight near 0.71 lb (0.32 kg). In practice, the 1756-L61 supports multi-tasking and large program structures, making it suitable for moderate-to-large automation environments that rely on the ControlLogix ecosystem for centralized control, data logging, and integration with other Rockwell Automation components.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657301098798,"sku":null,"price":2538.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_811895de-c387-4c22-8309-7653ac5f4875.jpg?v=1769467674","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-l61-controllogix-cpu-processor-module","provider":"PLG Automation ","version":"1.0","type":"link"}
