It provides 4K of user memory in Series B\/C variants, along with a DH-485 network interface for peer-to-peer communication and an RS-232 serial port for programming and diagnostics, enabling easy integration with existing Allen-Bradley hardware and software. The processor includes Flash-based backup memory and standard battery-backed RAM to preserve programs and data through power loss, with a typical power draw around 500 mA at 5 V and 175 mA at 24 V, making it compatible with common backplane power budgets. Installed in an SLC 500 chassis, this CPU handles both discrete and sequential I\/O control and adheres to the SLC 500 instruction set, serving as the computing core for automation tasks across industrial applications such as packaging lines, conveyors, and machine-tending processes.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657306046766,"sku":null,"price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_710f29da-9443-42df-a238-aceb5680a3f1.jpg?v=1769467745","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-l524-slc-500-cpu-processor-unit","provider":"PLG Automation ","version":"1.0","type":"link"}
