It installs in a 1747-series chassis and supports up to 4096 discrete inputs and 4096 discrete outputs, enabling expansive control schemes. The unit provides DH+ communications and an RS‑232 serial port for programming, and it supports DH‑485 networking for remote I\/O connections. Programming is performed with RSLogix 500, the standard software for SLC 500 family controllers. Key performance figures include a typical scan time of 4.8 ms per 1K of program memory and a bit execution time of 2.4 µs for XIC logic, delivering responsive enough performance for mid‑scale automation tasks. Power is supplied at 5 V DC with a typical load around 90 mA, and there are memory backup options via 1747‑M1 or 1747‑M2 modules to preserve data during power interruptions. Overall, the 1747‑L524 represents a robust 4K‑memory, DH+\/DH‑485 capable processor ideal for upgrading or maintaining mid‑life SLC 500 installations while preserving compatibility with a wide range of 1747 I\/O modules and RSLogix 500 project files.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New Surplus No Box","offer_id":51658960404782,"sku":null,"price":251.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_38ff297c-2f90-4f32-a374-ac62c6ce764a.jpg?v=1769526005","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l524-slc-500-series-processor","provider":"PLG Automation ","version":"1.0","type":"link"}
