The Allen-Bradley 2711-B5A5 PanelView 550 is a 5.5-inch monochrome operator terminal (KEY/TOUCH MONO) that provides local HMI visualization with both keypad and touchscreen input for straightforward machine interfaces. It is AC-powered from an external supply in the 85–264 V ac range and features a 256 × 128 pixel display, enabling concise status indicators and simple graphics in a compact package. The unit includes an RS-232 serial port configured for DH-485 communications to PLCs, along with a second RS-232 printer port for data output, consistent with the PanelView 550 family’s standard serial options. As part of the PanelView 550 family, this model is designed to work with SLC 500, PLC-5, and MicroLogix controllers, supporting DH-485 and DF1 full duplex communications, with optional Remote I/O and DeviceNet via appropriate modules. This catalog number (2711-B5A5) represents a compact, entry-level operator terminal suited for small to mid-size industrial applications where space is constrained and simple data presentation and input are sufficient.
