Allen-Bradley 2711-NL1 LED Backlight for PanelView 550

Allen-Bradley 2711-NL1 LED Backlight is a replacement illumination module for PanelView 550 LCD terminals, engineered to replace the original backlight in PV550 configurations such as 2711-K5A12 and 2711-B5A12. This LED-based backlight provides bright, even illumination of the PV550 display and is designed for long life, with an estimated service life around 20,000 hours. It operates from a 5-volt supply and consumes about 5 watts (roughly 1 amp) during operation. As a dedicated replacement backlight assembly, it restores screen readability when the previous lamp dims or fails, preserving the PV550’s viewing clarity without replacing the entire terminal. The NL1 backlight is intended for use with Allen-Bradley PanelView 550 terminals and is packaged as a terminal accessory replacement, enabling a straightforward swap to maintain display performance. When replacing, ensure the equipment is powered down and the backlight module is properly seated in the PV550 backlight cavity to achieve uniform brightness across the LCD panel.
