By combining the CPU, a 24V DC power supply, and a high-density mix of digital, analog, and high-speed I\/O into a single housing, it provides a cost-effective and space-saving solution. It is particularly well-suited for standalone machines, process skids, and distributed control systems that require EtherNet\/IP connectivity and integrated analog processing without the complexity of a large modular rack.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eAllen-Bradley (Rockwell Automation)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSeries:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCompactLogix (Packaged Controller)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1769-L23E-QBFC1B\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eUser Memory:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e512 KB (Battery-backed)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDigital I\/O:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e16 × 24V DC Inputs; 16 × 24V DC Outputs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAnalog I\/O:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e4 Differential\/Single-ended Inputs; 2 Single-ended Outputs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Speed Counters (HSC):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e4 Channels\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCommunication Ports:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1x EtherNet\/IP (10\/100 Mbps); 1x RS-232 (DF1\/ASCII)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eExpansion Capacity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSupports up to 2 additional 1769 modules\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePower Supply:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e24V DC Input (Integrated)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMounting:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDIN Rail or Panel Mount\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eBattery:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1769-BA (Replacement lithium battery for data retention)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIntegrated Multi-Function I\/O:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe \"QBFC\" designation highlights its rich onboard I\/O, including high-speed counters for motion feedback and analog channels for temperature or pressure monitoring.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSeamless Networking:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFeatures an embedded RJ45 EtherNet\/IP port for high-speed communication with HMIs, SCADA systems, and other controllers using CIP (Common Industrial Protocol).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLegacy Connectivity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe isolated RS-232 port supports DF1 and ASCII protocols, allowing for easy integration of legacy serial devices like barcode scanners and modems.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCompact Footprint:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIdeal for mounting in shallow enclosures or limited-space control panels where a standard modular PLC would be too large.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eBattery-Backed Data:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUnlike the newer 5370 series which uses SD cards, this L23E model uses a 1769-BA battery to maintain the 512 KB of volatile user RAM during power cycles.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":46556280193214,"sku":"1769-L23E-QBFC1B","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/allen-bradley-1769-of4-compact-i-o-modules-zpeddqjuxlp.png?v=1775527245","url":"https:\/\/www.autooiltech.com\/products\/allen-bradley-1769-l23e-qbfc1b-programmable-logic-controller","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
