It provides DH+ and RS-232 serial communications for legacy network connectivity, enabling integration with older Allen-Bradley devices and field equipment. The processor targets compact to mid-size applications with a program scan time of about 0.9 milliseconds and an I\/O scan time of roughly 0.225 milliseconds per keyword, addressing 4,096 input words and 4,096 output words, suitable for straightforward control tasks. Power characteristics specify a current draw of 1.0 A at 5 V DC and 200 mA at 24 V DC, reflecting typical installation conditions in panel-mounted SLC 500 systems. This CPU is designed for reliable operation in legacy automation environments, where compact hardware with DH+ and RS-232 connectivity supports simple machine control, sequencing, and data collection tasks without migrating to newer protocols. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658959061294,"sku":null,"price":435.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1478de98-80eb-4ccd-9b49-200ac37779f3.jpg?v=1769525983","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l541-slc-500-plc-processor","provider":"PLG Automation ","version":"1.0","type":"link"}
