It provides 20 discrete I\/O points in a fixed controller: 12 inputs rated for 120 VAC and 8 outputs implemented as triac drivers for AC loads. The module includes 1K of user memory (Rev B) for ladder logic programs. As a fixed-hardware style controller, the 1747-L20B is designed to mount in a 1747 backplane chassis and interact with compatible I\/O modules to form a complete control system. Programming is performed with RSLogix 500, following the standard SLC 500 workflow for ladder logic and discrete control. Typical applications include simple machine control, packaging lines, and small automation tasks that require a single processor to manage multiple I\/O points and basic sequencing.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658961584430,"sku":null,"price":167.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_56fc058a-91c6-4686-8c4d-d5ce2256b115.jpg?v=1769526022","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l20b-slc-500-processor-module","provider":"PLG Automation ","version":"1.0","type":"link"}
