It provides 8K of memory for user program and data and includes an RS-232 port for direct programming and a DH-485 port for serial network communication with other controllers and devices. This module ships with OS 1747-OS302 firmware (Series C), FRN 6, enabling compatibility with RSLogix 500 projects built for 5\/03 CPUs. As part of the 1747-L531 family, it is commonly used in small to mid-size automation tasks such as conveyors, pumps, and packaging lines where a robust, rack-mounted processor is required. Designed to operate within Rockwell Automation's SLC-500 ecosystem, it supports standard SLC 500 I\/O addressing and sequencing through the built-in processor and data highway network. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658960372014,"sku":null,"price":229.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_af2c0e49-78d7-4bc4-9525-7fcdda71208c.jpg?v=1769526005","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l531-programmable-logic-controller-processor-module","provider":"PLG Automation ","version":"1.0","type":"link"}
