It is commonly installed in SLC 500 chassis across manufacturing plants, material handling systems, water treatment facilities, and process control applications where reliable PLC control is required, and is frequently used by maintenance teams, original equipment manufacturers (OEMs), and system integrators for repairs, legacy PLC replacement, and rack upgrades. Key specifications include 16 KB user memory for program storage, DH-485 and RS-232 serial communication ports for networked control and remote diagnostics, mounting in a 1746 SLC 500 chassis slot, and programming with RSLogix 500, with power supplied by the SLC 500 power supply module. Common replacements listed for this processor include Allen-Bradley 1747-L532 and 1747-L533, and Siemens 6ES7214-1AG40-0XB0, reflecting its role in legacy automation ecosystems that span multiple manufacturers.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Surplus Original Box","offer_id":50558359699758,"sku":"Surplus Original Box","price":442.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/1747-L531.jpg?v=1752217000","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l531-cpu-processor-unit-module","provider":"PLG Automation ","version":"1.0","type":"link"}
