Allen-Bradley 2711R-T4T PanelView 800 HMI Terminal

The Allen-Bradley 2711R-T4T PanelView 800 HMI Terminal is a compact touchscreen operator interface designed for industrial automation, typically mounted in control panels and small machinery to provide real-time monitoring and control of PLC-driven processes. It offers straightforward integration with micro and small PLC controllers and is commonly used for replacement or retrofit projects that require visualization in tight automation spaces. Key specifications include a 4.3-inch TFT LCD display with 480 × 272 resolution, 24 V DC supply, approximately 128 MB of memory, and a high-performance CPU in the 800 MHz class, with a power draw around 9 W. Communication ports include Ethernet, USB, and serial RS-232/422/485, and the unit is panel-mount capable with an operating temperature range of 0°C to 50°C. Common replacements are 2711R-T7T, 2711R-T10T, and 2711P-T7C21D8S. Designed for operator interaction and visualization on small production lines, packaging machines, and standalone equipment, the PanelView 800 delivers compact HMI functionality in industrial settings.
