high-performance SLC 5\/05 processor designed for industrial applications requiring fast execution, networked connectivity, and large I\/O capacity. As part of the SLC 500 architecture, it installs into any SLC chassis and communicates seamlessly with partner modules across the backplane. The controller includes a built-in RS-232 serial port and an Ethernet port, enabling flexible communication with HMIs, SCADA systems, peer PLCs, and plant-wide networks. Ethernet connectivity allows direct integration without additional communication modules, simplifying IIoT or enterprise-layer integration. With 32 KB of battery-backed RAM, the 1747-L552 supports complex program structures and extensive data handling tasks. It also supports a maximum of 30 slots across up to 3 interconnected chassis, allowing scalable architectures and distributed I\/O layouts via Remote I\/O adapters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e32 KB user memory (battery-backed RAM)\u003c\/li\u003e\n\u003cli\u003eBuilt-in Ethernet and RS-232 communication\u003c\/li\u003e\n\u003cli\u003eSupports up to 4096 digital inputs and 4096 digital outputs\u003c\/li\u003e\n\u003cli\u003eExecutes 0.9 ms\/K-word typical program scan\u003c\/li\u003e\n\u003cli\u003eSupports up to 30 I\/O slots across 3 chassis\u003c\/li\u003e\n\u003cli\u003eBOOTP-enabled Ethernet configuration\u003c\/li\u003e\n\u003cli\u003eBattery backup with capacitor hold-up\u003c\/li\u003e\n\u003cli\u003eCompatible with all SLC 500 modules and chassis\u003c\/li\u003e\n\u003cli\u003eSupports 48 total communication connections\u003c\/li\u003e\n\u003cli\u003eIdeal for mid- to large-scale automation applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA powerful SLC 5\/05 processor offering Ethernet connectivity, large memory capacity, and broad I\/O support for scalable industrial automation.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":47192120197418,"sku":"1747-L552","price":2985.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/1747-L552.png?v=1784565538","url":"https:\/\/iqelectro.com\/products\/allen-bradley-1747-l552-slc-5-05-processor-32k-memory-ethernet-rs-232","provider":"IQElectro","version":"1.0","type":"link"}
