Allen-Bradley 2711-B5A15 HMI Panel PanelView 550 Mono Touch Screen

The Allen-Bradley 2711-B5A15 PanelView 550 Mono Touch Screen is a 5.5-inch monochrome HMI terminal designed for operator interaction with Rockwell Automation PLCs such as SLC 500, PLC-5, and MicroLogix families. It uses a blue-mode monochrome LCD with a 256 x 128 pixel display area of about 120 x 60 mm, and a backlight rated at 100,000 hours; the touch screen offers 128 touch cells and supports up to 1,000,000 activations. The runtime memory is about 170 KB for application data with 240 KB of nonvolatile RAM for text and bitmaps, and it runs PanelBuilder32 software for development. Power is via AC input (85–264 VAC, 47–63 Hz) with a maximum power draw of 45 VA; communication options include an RS-232 printer port (supporting 1200/2400/9600 baud) and a ControlNet port, with additional network compatibility through standard Rockwell interfaces.
