It provides 8K of user memory and runs 1747-OS302 Series C firmware with FRN 5, FRN 6, or FRN 7 for stable operation. The module exposes DH-485 and RS-232 serial communications to support standard SLC 500 networks and programming interfaces, and it draws 500 mA from a 5 V backplane (175 mA at 24 V). This processor is identified by the 1747-L531 designation within the SLC 500 lineup and is compatible with the broader 1747 family of CPUs.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657303949614,"sku":null,"price":188.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_177c5134-f9c6-4995-b721-b4a033e5354c.jpg?v=1769467717","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l531-slc-500-processor-module","provider":"PLG Automation ","version":"1.0","type":"link"}
