Designed for robust machine-level visualization, this terminal facilitates real-time process monitoring and direct interaction with programmable logic controllers (PLCs). It is engineered for 24 VDC industrial environments, providing a reliable alternative to traditional physical switch panels in applications such as automotive assembly, water processing, and material handling.\u003c\/p\u003e\u003ch3\u003eCommunication and Memory\u003c\/h3\u003e\u003cp\u003eThis unit features a dual-interface architecture to support both network connectivity and peripheral logging. The primary communication port is an integrated Ethernet interface, enabling low-latency data exchange over EtherNet\/IP architectures. A secondary RS-232 serial port is provided for dedicated printer output or firmware updates. The terminal includes 170 KB of application runtime RAM and 240 KB of non-volatile memory, with an integrated PCMCIA ATA slot available for expanded storage, recipe management, and data logging.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIntegrated membrane keypad with 10 assignable function keys (F1-F10), numeric input, and navigation clusters.\u003c\/li\u003e\n\u003cli\u003e5.5-inch monochrome transflective LCD (blue mode) with long-life LED backlight.\u003c\/li\u003e\n\u003cli\u003eField-serviceable backlight (MTBF 100,000 hours).\u003c\/li\u003e\n\u003cli\u003eHardware-based real-time clock (RTC) for precise event time-stamping.\u003c\/li\u003e\n\u003cli\u003eStatus diagnostics via dedicated COMM (green) and Fault (red) LEDs.\u003c\/li\u003e\n\u003cli\u003eNEMA 12, 13, 4X and IP54\/IP65 environmental ratings for indoor industrial use.\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-K5A20L1\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 (5.3 inch viewable)\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\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (18-32 VDC range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterfaces\u003c\/td\u003e\n\u003ctd\u003e1 x Ethernet, 1 x RS-232 (Printer)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory\u003c\/td\u003e\n\u003ctd\u003e170 KB RAM \/ 240 KB Non-volatile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.14 kg\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 burrs to maintain the integrity of the NEMA\/IP seal.\u003c\/li\u003e\n\u003cli\u003eUse appropriate shielded Ethernet cabling to minimize EMI in high-noise industrial environments.\u003c\/li\u003e\n\u003cli\u003eVerify that the 24 VDC power supply is within the 18-32 VDC range before connection to prevent damage.\u003c\/li\u003e\n\u003cli\u003eMaintain adequate clearance around the unit for ventilation and access to the PCMCIA slot.\u003c\/li\u003e\n\u003cli\u003eAlways power down the terminal before inserting or removing PCMCIA cards or performing wiring maintenance.\u003c\/li\u003e\n\u003cli\u003eEnsure proper grounding of the chassis to the control cabinet frame to reduce electrical interference.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eCan the backlight be replaced in the field?\u003c\/strong\u003e Yes, the LED backlight is field-serviceable using the 2711-NL1 replacement part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the primary purpose of the RS-232 port?\u003c\/strong\u003e The RS-232 port is configured specifically for printer communication or firmware deployment tasks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this unit support external storage?\u003c\/strong\u003e Yes, the terminal features an integrated PCMCIA ATA slot for localized data logging and recipe storage.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":51008912031996,"sku":"2711-K5A20L1","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_56bfe2e6-9085-46a2-acc5-e653096258ff.jpg?v=1787591978","url":"https:\/\/www.electronicplc.com\/es\/products\/2711-k5a20l1-allen-bradley-panelview-550-ethernet-terminal","provider":"Electronic PLC","version":"1.0","type":"link"}
