It offers 32K words of user memory for ladder logic and data, and supports up to 4,096 discrete inputs and 4,096 discrete outputs across a compatible SLC 500 chassis. The unit includes one Ethernet port (10 Mbps) and one RS-232 serial port for programming, diagnostics, or serial device connections. Performance specifications include an approximate program scan time of 0.9 ms and an I\/O scan time around 0.225 ms, enabling responsive control for typical small-to-mid-size applications. Programming is typically conducted with RSLogix 500, and the 1747-L552 can be augmented with an EtherNet\/IP solution such as the 1747-AENTR Ethernet\/IP adapter to extend network connectivity. This processor is designed for legacy SLC 500 systems requiring Ethernet and RS-232 integration, offering a straightforward path to networked control while retaining familiar RS-232 interfacing and ladder-based programming.\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46279502692586,"sku":null,"price":3625.0,"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-l552-slc-500-ethernet-controller","provider":"GTG Hardware","version":"1.0","type":"link"}
