Allen-Bradley 77144-167-51-A Backlight For PanelView 1000

Allen-Bradley 77144-167-51-A is a field-replaceable backlight assembly for PanelView 1000 human-machine interface terminals, engineered to restore uniform illumination to the PV1000 display when the original light source has degraded, helping maintain legibility of graphics, text, and status indicators. It is commonly cataloged with related entries 77144-062 and 77144-226 as backlight replacements for PanelView 1000 units, reflecting multiple catalog entries that customers may encounter across PV1000 revisions. Rockwell's published guidance for PV1000 backlight replacements—2711-IN020, Display Backlight for PanelView 1000 Terminals—plus references to backlight families such as NL4 for PV1000 color terminals and NL7/NL9/NL10 for Series C PV1000 backlights, confirms the intended use within the PanelView 1000 ecosystem. When replacing, power down the device and follow the installation procedures exactly to minimize the risk of damage to the display module or controller and to ensure the backlight operates correctly.
