It provides 16,000 words of user memory and supports up to 4,096 I\/O points, enabling it to run standard SLC 500 ladder logic programs while coordinating a mix of digital and analog modules in a compact chassis. The onboard RS‑232 port supports DF1 serial communications to peripheral devices, and the integrated Ethernet interface allows networked data exchange with host PCs, HMIs, or other controllers. As a long‑standing member of the SLC 500 ecosystem, the 1747‑L551 is typically installed in a compatible SLC 500 rack to manage I\/O timing, sequencing, and remote communications across both serial and Ethernet networks. Note: Rockwell Automation announced the SLC 5\/05 family, including the 1747‑L551, is discontinued for sale as of December 31, 2021. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46279502561514,"sku":null,"price":972.0,"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-l551-enet-rs-232-controller","provider":"GTG Hardware","version":"1.0","type":"link"}
