It provides 16K words of user memory and can control up to 4,096 I\/O points, with a program scan time of about 0.9 ms per keyword and an I\/O scan time of roughly 0.225 ms, enabling responsive control of sequencing and discrete I\/O tasks. The processor includes built-in DH+ and RS-232 ports for DH network connectivity and programming with RSLogix 500, and it uses flash-based backup memory to retain data when power is removed. Rockwell Automation discontinued the 1747-L541 as of December 31, 2021, reflecting its status as a legacy, non-Ethernet SLC 500 CPU. This CPU is best suited for legacy automation setups that rely on RSLogix 500 tooling and DH+ networks, delivering a straightforward, cost-effective solution for simple machine control, conveyor sequencing, and batch-style processes in older systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659704369454,"sku":null,"price":260.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_0b7ed05a-3501-4570-9a66-09cda2678099.jpg?v=1769529755","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l541-slc-500-programmable-logic-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
