Allen-Bradley 2711-K5A5 PanelView HMI Touchscreen

Allen-Bradley 2711-K5A5 PanelView 550 Standard Operator Terminal is a compact, 5.5-inch monochrome HMI with a keypad interface designed for straightforward local control and monitoring. The display is a blue-mode monochrome LCD with 256 x 128 pixel resolution, backlit by an LED with an expected life of about 100,000 hours. It uses a battery-backed real-time clock to timestamp critical data, and the keypad features 10 function keys (F1–F10) for quick operator input. The unit is powered from 18–30 VDC (24 V nominal), with a maximum power draw of 18 W. For communications, it provides an RS-232 port (DH-485) and is compatible with the broader PanelView 550 communications ecosystem, including EtherNet/IP, DeviceNet, DH+, ControlNet, Remote I/O, DH-485 and RS-232 (DF1) depending on configuration and adapters. In terms of memory, it offers about 170 KB of application runtime memory and 240 KB of nonvolatile RAM for objects, text, and bitmaps, plus support for an ATA memory card for on-device data storage. Software to program and deploy screens is PanelBuilder32, and the terminal is part of the PanelView 550 family known for reliable, compact operator interfaces in industrial environments. This model is a non-touchscreen keypad HMI suitable for simple, local operator monitoring and control tasks where a small-form, durable PanelView terminal is preferred.
