Allen-Bradley 2711-B5A2 PanelView 550 Graphic Terminal

Allen-Bradley 2711-B5A2 PanelView 550 is a 5.5-inch monochrome operator terminal with a keypad and touchscreen input, designed for local HMI tasks on industrial machines. This PanelView Standard 550 variant runs off an AC power supply and is built to sit in control panels where a compact, rugged display is needed. It communicates with Allen-Bradley controllers such as SLC 500, PLC-5, and MicroLogix over DH-485 (RS-232), with DF1 full-duplex, Remote I/O, or DeviceNet options available when paired with the appropriate communication modules. The model is associated with firmware FRN 1.07, reflecting the classic PV550 revision levels. The 2711-B5A2 designation identifies the PV550 5.5-inch, key-and-touch monochrome terminal in Rockwell Automation’s standard-series lineup. Typical applications include machine-level operator input and status visualization in legacy AB control systems, where a compact HMI provides direct interaction without requiring newer PanelView Plus or Ethernet-enabled hardware. The combination of a 5.5-inch display, monochrome input methods, and DH-485 communications makes it a go-to for retrofitted or existing SLC/PLC-5 installations that rely on serial AB networking.
