It supports DF1, DH-485, or ASCII on Channel 0, enabling direct connection to programming consoles, HMIs, or other controllers over RS-232, and provides Ethernet networking for PLC-to-SCADA or PLC-to-PLC communications. With a program scan time around 0.9 milliseconds and an I\/O scan time near 0.225 milliseconds (depending on I\/O load), the L552 fits in up to 30 backplane slots in a compatible SLC chassis, offering a straightforward option for legacy systems needing Ethernet access. This CPU is part of the SLC 5\/05 family and thus combines traditional DH+ and RS-232 interfaces with Ethernet connectivity for mixed-network environments; firmware configurations vary by production, and several listings reference FRN 13 for this model.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658956964142,"sku":null,"price":2320.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_eb4be153-7379-429b-9db1-389e5454ec87.jpg?v=1769525954","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l552-slc-5-05-cpu-module","provider":"PLG Automation ","version":"1.0","type":"link"}
