Allen-Bradley 2711-K5A20L1 PanelView 550 With Ethernet

The Allen-Bradley 2711-K5A20L1 PanelView 550 with Ethernet is a compact 5.3‑inch monochrome keypad HMI terminal designed to run PanelBuilder32 applications and connect to Rockwell Automation PLCs over EtherNet/IP. Its display provides a 4.75 x 2.38 inch (120 x 60 mm) active area with a 256 x 128 pixel native resolution and blue backlight, paired with a stainless‑steel domed membrane keypad featuring 10 function keys (F1–F10) and durable actuation rated at about one million presses. Power is supplied from 18–30 V DC (24 V nominal) and it draws up to 18 W; it stores runtime data in 170 KB of application memory and 240 KB of nonvolatile RAM, with ATA memory card support for program and data storage, and it includes a battery‑backed real‑time clock. The panel includes an RS-232 printer port supporting 1200/2400/9600/19200 baud and Ethernet connectivity for remote monitoring and integration with automation networks, using PanelBuilder32 software for configuration and deployment, making it suitable for operator interfaces on automated production lines requiring real‑time data display, alarms, and input from the machine operator.
