This CPU provides 32 KB of user memory for ladder logic and data and is intended for use in a 1747 modular chassis with a RUN\/PROG\/FLT front switch and a detachable key for secure mode selection. It offers DH+ (Data Highway Plus) and RS-232 serial communications for programming and data exchange, and is compatible with the RSLogix 500 programming environment. The 1747-L542 runs on 5–24 V DC supply and is available in standard form or conformal-coated variant (1747-L542-CC) for harsh environments. As part of the Series 1 SLC 500 ecosystem, this CPU supports up to 8,192 digital I\/O points across configured I\/O modules, enabling scalable control for manufacturing equipment. It includes Flash EEPROM for non-volatile program storage, preserving logic across power cycles and simplifying field updates in legacy automation tasks.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658912727342,"sku":null,"price":517.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_21641ca5-172d-4d06-a668-1a47c34e6279.jpg?v=1769525436","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l542-slc-500-cpu-processor-module","provider":"PLG Automation ","version":"1.0","type":"link"}
