产品介绍
The Allen-Bradley 2711-K5A5L1 PanelView 550 Operator Interface is a compact industrial HMI designed for machine-level monitoring and basic process control applications. As part / the PanelView 550 series, it is built to provide stable operator interaction in small to medium automation systems where simplicity and reliability are more important than advanced graphics.
This model features a 5.5-inch monochrome LCD display with a resolution / 256 × 128 pixels. The screen is optimized for text-based data presentation, alarms, and simple status indicators, ensuring clear readability in continuous industrial operation. Its keypad-only input design provides durable and reliable operation, especially in environments where touchscreen use is not preferred.
The 件 supports RS-232 (DH-485) communication, making it suitable for integration with Allen-Bradley PLC systems such as SLC 500 and MicroLogix controllers. Powered by a 24 VDC supply, it is commonly used in control cabinets where DC power distribution is standard.
With its compact size, stable communication capability, and proven industrial design, the 2711-K5A5L1 is widely applied in legacy system maintenance and basic automation control tasks.
