It provides up to 16,000 words of user memory (16K words) and supports up to 4,096 digital inputs and 4,096 digital outputs, enabling large I\/O configurations in a compact form. With a program scan time of about 0.9 ms and an I\/O scan time around 0.225 ms, this CPU handles discrete control tasks efficiently in industrial environments. Installed in a compatible SLC 500 chassis, it is suitable for applications such as conveyors, automated packaging, and general machine control where a robust, modular PLC with DH+\/RS-232 connectivity is advantageous.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46243873816810,"sku":null,"price":218.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1747-l541-ser-c-rev-7-5-04-processor-unit-w-1747-os401-serc-frn-3","provider":"GTG Hardware","version":"1.0","type":"link"}
