2711-B5A2 | Allen-Bradley PanelView 550 Operator Terminal, 5.5" DH-485

• Communication Port: The terminal is equipped with a built-in DH485 port, which is a standard communication protocol commonly used in Allen-Bradley systems for connecting to PLCs, PACs, and other networked devices.
• Communication Cable: The 1747-C10 cable is typically used to connect the 2711-B5A2 to the target device.
• Network Integration: The DH485 network enables the operator terminal to exchange real-time data and commands with controllers, ensuring that operators can monitor process variables, issue commands, and receive feedback instantly.
• Applications: This connectivity is particularly valuable in environments where reliable, deterministic communication is essential for maintaining process integrity and efficiency.

Yes, the 2711-B5A2 offers a dual-input interface designed to enhance operator flexibility and usability. The terminal features a resistive touchscreen with 128 touch cells, rated for up to 1 million actuations, allowing operators to interact directly with on-screen elements by pressing designated areas. Additionally, the unit includes a 10-key function keypad (F1-F10), enabling quick access to frequently used commands, navigation, and screen selections.

The 2711-B5A2 is designed to accommodate a wide range of industrial power environments. It accepts an input voltage from 85 to 264 Volts AC, with an operating frequency of 47 to 63 Hz. This broad voltage and frequency range allows the terminal to be deployed globally without the need for additional power conditioning or voltage conversion equipment.

• Display: The 2711-B5A2 features a 5.5-inch monochrome LCD blue mode display with a resolution of 256 x 128 pixels, providing clear visualization of process variables and operator screens.
• Display Area: 120 x 60 mm (4.75 x 2.38 in.), offering ample space for displaying key information, alarms, and graphical representations of processes.
• Application Memory: The device includes 170KB of application runtime memory and 240KB of nonvolatile memory to store application objects, text, and bitmaps, supporting detailed graphics and screen configurations.
• Touchscreen Performance: The touchscreen is arranged in a 24-column by 16-row grid, with each cell designed to register reliably across its 1 million press lifespan.

These specifications make the 2711-B5A2 suitable for a range of process monitoring and control tasks where clarity and responsiveness are essential.

The 2711-B5A2 is designed for straightforward installation on a panel surface, using standard mounting hardware that ensures secure placement in an industrial enclosure. The installation process is supported by a range of optional accessories, including stainless steel bezels for enhanced durability, anti-glare overlays to improve screen visibility in high-light environments, and function key legend inserts for quick operator reference.
