Product Description
The obsolete Allen-Bradley PanelView 550 (2711-B5A5) is a 5.5-inch monochrome HMI terminal with a 256x128 resolution, keypad and touchscreen input, and an RS-232 (DH-485) communication port (requiring 2711-NC13 cables for network connection). It lacks a printer port but features a 100,000-hour LED backlight (replaceable with 2711-NL1), a real-time clock with battery backup, and ATA memory card support. It operates on 120VAC (47-63 Hz), has 170KB RAM and 240KB non-volatile memory, and dissipates 20 Watts (69 BTU/hour). Its operating temperature range is 32-131F, storage temperature range is -4-158F, and relative humidity is 5-95% (up to 30C). It's designed for altitudes below 200 meters and can be enclosed with NEMA Type 12, 13, 4x, IEC IP54, or IP65 enclosures. This early PanelView model facilitates machine/process control with alarm handling, security, trending, and recipe functions, allowing operators to interact via ten programmable function keys or the touchscreen, both rated for 1 million actuations. It supports 85-264VAC input and memory expansion via ATA card (2MB-32MB).
Is Your Device Showing These Signs?
The Allen Bradley 2711-B5A5 HMI commonly experiences failures related to the touchscreen membrane, resulting in unresponsive or inaccurate user input. Backlight degradation is a frequent issue, causing diminished screen visibility and requiring backlight replacement. Communication problems arise due to faulty communication ports or corrupted firmware, necessitating port repair or firmware reflashing. Power supply failures manifest as intermittent operation or complete unit shutdown, demanding power supply repair or replacement. Logic board component failures lead to operational errors and require component-level repair.
