Excellent PLC
Product Introduction
The Allen-Bradley 2711-K5A1 PanelView 550 Operator Interface is a reliable and compact HMI terminal designed for industrial automation applications requiring a small but functional operator interface. As part of the PanelView 550 series, this model provides essential visualization and control features for small- to medium-sized systems, offering a balance between functionality and cost-efficiency.
Equipped with a 5-inch monochrome display at 256 × 128 pixel resolution, the unit provides clear visualization of key process parameters, system status, and alarms. The integrated keypad allows operators to navigate screens, input values, and execute commands efficiently. The interface supports Remote I/O and RS-232 communication, enabling easy integration with Allen-Bradley controllers and other industrial devices.
The device operates on 100–240 VAC input at 50/60 Hz, ensuring compatibility with standard industrial power sources. Its panel-mount design, lightweight construction (1.2 kg), and compact dimensions make it suitable for OEM equipment, small machinery, and space-constrained control panels.
