The Allen Bradley 2711-B5A1 PanelView 550 is a compact Human Machine Interface (HMI) terminal designed to provide operators with reliable monitoring, control, and visualization capabilities in industrial automation environments. As part of the PanelView Standard series, this model is widely used in legacy Rockwell Automation systems where stable, simple, and proven operator interaction is required.
Built for small to mid-scale automation applications, the 2711-B5A1 combines a 5.5-inch monochrome display with keypad and touchscreen input, offering an efficient balance between usability and durability. It is especially suited for systems where rugged performance and long service life are more critical than high-resolution graphics.
Despite being an older-generation HMI, the PanelView 550 series remains in service across manufacturing plants worldwide due to its reliability, straightforward configuration, and strong compatibility with Remote I/O-based control architectures.
