This visualization station establishes high-speed, deterministic communication and real-time plant-floor monitoring by connecting directly to industrial automation controllers. Optimized for enterprise-level control networks, it is widely implemented in wastewater treatment facilities, food production lines, and continuous manufacturing plants. The hardware processes complex graphical representations and alarm tables locally, which significantly decreases processing overhead on the host programmable logic controller and minimizes system diagnostic downtime.\u003c\/p\u003e\u003ch3\u003eIndustrial Networking and Memory Architecture\u003c\/h3\u003e\u003cp\u003eThe hardware platform integrates a dual-channel communication subsystem featuring native network connectivity and a dedicated peripheral interface. The primary communication port utilizes an onboard industrial Ethernet (EtherNet\/IP) interface, ensuring noise-immune, low-latency register mapping and peer-to-peer data transfers across standard TCP\/IP network structures. An auxiliary RS-232 serial configuration functions strictly as an isolated printer port, allowing immediate, hardcopy logging of system fault banners without introducing traffic onto the primary control network. Local memory architecture consists of 170 KB of volatile RAM for application runtime and 240 KB of non-volatile storage, which can be expanded via a built-in PCMCIA ATA flash card slot to support large localization databases and historical trend storage.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRugged membrane keypad interface with 10 assignable function keys (F1-F10)\u003c\/li\u003e\n\u003cli\u003eMonochrome transflective LCD blue mode display with long-life LED backlight\u003c\/li\u003e\n\u003cli\u003eIntegrated EtherNet\/IP connectivity for high-speed controller communication\u003c\/li\u003e\n\u003cli\u003eField-serviceable backlight and battery-backed real-time clock\u003c\/li\u003e\n\u003cli\u003eNEMA 4X\/12\/13 and IP65 environmental protection for harsh industrial conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis operator terminal is designed for use in diverse industrial environments, including:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWastewater treatment and water management systems\u003c\/li\u003e\n\u003cli\u003eFood and beverage processing lines\u003c\/li\u003e\n\u003cli\u003eContinuous manufacturing and assembly automation\u003c\/li\u003e\n\u003cli\u003eGeneral machine control and diagnostic monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e2711-K5A20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003ePanelView 550 Standard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay Size\u003c\/td\u003e\n\u003ctd\u003e5.5 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e256 x 128 Pixels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBacklight Life\u003c\/td\u003e\n\u003ctd\u003e100,000 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRAM\u003c\/td\u003e\n\u003ctd\u003e170 KB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNon-volatile Memory\u003c\/td\u003e\n\u003ctd\u003e240 KB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eEthernet (EtherNet\/IP), RS-232 (Printer)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e85 to 264 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e47 to 63 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eNEMA 4X, 12, 13; IP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the panel cutout is clean and free of debris before mounting the terminal.\u003c\/li\u003e\n\u003cli\u003eUse the provided mounting clips to secure the unit to the enclosure, ensuring an even seal against the gasket to maintain NEMA\/IP ratings.\u003c\/li\u003e\n\u003cli\u003eVerify that the power supply is within the 85-264 VAC range before applying power.\u003c\/li\u003e\n\u003cli\u003eMaintain proper clearance around the unit for adequate ventilation and access to the PCMCIA slot.\u003c\/li\u003e\n\u003cli\u003eRoute communication cables away from high-voltage power lines to prevent EMI interference.\u003c\/li\u003e\n\u003cli\u003eAlways power down the device before inserting or removing PCMCIA flash cards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs the backlight on this unit field-replaceable?\u003c\/strong\u003e\u003cbr\u003eYes, the LED backlight is field-serviceable using the 2711-NL1 replacement part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the primary function of the RS-232 port?\u003c\/strong\u003e\u003cbr\u003eThe RS-232 port is configured strictly as a printer port for hardcopy logging of system events and faults.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the memory be expanded?\u003c\/strong\u003e\u003cbr\u003eYes, the unit includes a PCMCIA ATA flash card slot for expanding storage for localization databases and historical trends.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":50965279998204,"sku":"2711-K5A20","price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_39fb7f90-6fde-42ce-9788-4ced22b7ea22.jpg?v=1786407317","url":"https:\/\/www.electronicplc.com\/products\/2711-k5a20-panelview-550-hmi-ethernet-operator-terminal","provider":"Electronic PLC","version":"1.0","type":"link"}
