As a member of the 1747 processor family, this module plugs into a 1747 backplane and executes ladder logic programs created with RSLogix 500, making it suitable for compact, discrete control, sequencing, and machine-control tasks on small to mid-sized manufacturing lines where a legacy PLC solution remains appropriate. The 1747-L542 is documented in Rockwell Automation’s SLC 500 documentation as a 5\/04 series processor, with compatibility references to other 1747‑L54x processors and associated memory modules. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46279502168298,"sku":null,"price":1805.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-077.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1747-l542-c-slc-500-slc-5-04-cpu-processor-rs232-dh-32k","provider":"GTG Hardware","version":"1.0","type":"link"}
