Allen-Bradley 2711-B5A8 PanelView 550 HMI Display

The Allen-Bradley 2711-B5A8 PanelView 550 is a 5.5-inch monochrome HMI terminal with a keypad and touchscreen, featuring a blue-backlit LCD for operator interaction. This refurbished unit runs firmware revision 4.48 (DH FRN 4.48) and is powered by AC, aligning with the PanelView 550 legacy design. It communicates on a DH+ network and includes an RS-232 printer port for alarms or event printing, enabling straightforward data exchange with Rockwell controllers. The PanelView 550 family is designed for use with SLC 500, PLC-5, and MicroLogix controllers, supporting DH+ and DF1 networks and DeviceNet via appropriate modules. The 5.5-inch monochrome LCD provides clear text and basic graphics with a backlight rated for about 100,000 hours, making it suitable for compact on-machine operator interfaces in legacy Rockwell environments.
