Featuring a No Stored Energy (NSE) design, it is equipped with 3 MB user memory and a conformal coating for added protection in environments prone to moisture, dust, and corrosion. Integrated with a gigabit EtherNet\/IP port, this controller excels at high-speed communications, motion control, and I\/O processing. With advanced diagnostics, embedded security features, and support for controller-based change detection, the 1756-L81E-NSE streamlines project setup and long-term maintenance. This unit eliminates battery dependency by using an energy storage module, reducing downtime in critical control systems and simplifying lifecycle management for OT teams.\n\n\u003ch2\u003eKey Features of Allen Bradley 1756-L81E-NSE\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e3 MB user memory for complex automation logic\u003c\/li\u003e\n  \u003cli\u003eEmbedded gigabit EtherNet\/IP for high-speed I\/O\/motion control\u003c\/li\u003e\n  \u003cli\u003eConformal coating for harsh environments\u003c\/li\u003e\n  \u003cli\u003eSupports up to 100 EtherNet\/IP devices\u003c\/li\u003e\n  \u003cli\u003eEnergy storage module—no need for battery replacement\u003c\/li\u003e\n  \u003cli\u003eEnhanced diagnostics and troubleshooting via onboard display\u003c\/li\u003e\n  \u003cli\u003eAdvanced security: role-based access, digitally-signed firmware\u003c\/li\u003e\n  \u003cli\u003eChange detection and logging for system integrity\u003c\/li\u003e\n  \u003cli\u003eProgramming via Studio 5000 Logix Designer\u003c\/li\u003e\n  \u003cli\u003eMeets stringent industrial standards for temperature\/shock\/vibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 1756-L81E-NSE\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eMemory: 3 MB user memory, SD card support\u003c\/li\u003e\n  \u003cli\u003eCommunications: 1x Gigabit Ethernet\/IP port, 1x USB port\u003c\/li\u003e\n  \u003cli\u003eMax EtherNet\/IP nodes: 100\u003c\/li\u003e\n  \u003cli\u003eMax Digital I\/O: 128,000\u003c\/li\u003e\n  \u003cli\u003eMax Analog I\/O: 4,000\u003c\/li\u003e\n  \u003cli\u003eOperating temperature: 0°C to 60°C\u003c\/li\u003e\n  \u003cli\u003ePower dissipation: up to 6.2 W\u003c\/li\u003e\n  \u003cli\u003eWeight: approx. 0.394 kg\u003c\/li\u003e\n  \u003cli\u003eIsolation voltage: 50 V\u003c\/li\u003e\n  \u003cli\u003eCompliant with IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-14\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\nAllen Bradley 1756-L81E-NSE controllers serve vital roles in large-scale automation architectures requiring fast decision making and robust reliability. Typical installations include discrete manufacturing lines, process control systems, and material handling setups. The integrated gigabit EtherNet\/IP capabilities allow seamless connection to drives, remote I\/O, and safety devices, making it ideal for high-speed synchronized motion and complex sequencing applications. The conformal coating extends lifespan in challenging environments, such as chemical processing plants or mining operations, where atmospheric contaminants can be prevalent. Security features and change logging are suited for regulated industries like pharmaceuticals and food\/beverage, supporting audit trails and safeguarding intellectual property. Its compatibility with Studio 5000 Logix Designer software simplifies programming and system expansion across diverse industrial sectors.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/\" target=\"_blank\"\u003eLeadTime.ca – Industrial Automation Components \u0026amp; Repair Services\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/collections\/allen-bradley\" target=\"_blank\"\u003eView All Allen Bradley Products\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/blogs\/learning-center\/top-plc-brands-compared-siemens-allen-bradley-mitsubishi\" target=\"_blank\"\u003eTop PLC Brands Compared: Siemens, Allen Bradley \u0026amp; Mitsubishi\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1756-en2tr\" target=\"_blank\"\u003eAllen Bradley 1756-EN2TR EtherNet\/IP Module for ControlLogix Systems\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-5069-l320er\" target=\"_blank\"\u003eAllen Bradley 5069-L320ER CompactLogix Controller\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870784307499,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_fee2039d-23b7-455b-8ed2-305c3dc942ad.png?v=1723532128","url":"https:\/\/leadtime.ca\/products\/allen-bradley-1756-l81e-nse","provider":"LEADTIME","version":"1.0","type":"link"}
