Allen-Bradley 855R Indicator Light Green Screw-In Base

Allen-Bradley 855R Green Indicator Light with Screw-In Base is a round LED beacon in Rockwell Automation’s 855R signaling family, engineered for clear, unambiguous visual signaling on industrial equipment. The green, single-color LED provides bright, long-life illumination and is mounted via a screw-in base that simplifies field installation into standard panel cutouts or enclosure openings. The 855R lineup includes multiple LED modules that can be configured for steady illumination or other signaling modes depending on the exact variant; this green version emphasizes straightforward status indication in automation circuits. Common applications include indicating machine readiness, process running, or interlock states in control panels, conveyors, and production equipment where durable, visible signaling is required. Voltage and other electrical options for 855R beacons vary by model, with many mains-voltage variants (110–240 VAC) available; when selecting the specific part, verify the exact base code and voltage rating to ensure proper fit and electrical compatibility with your system. As with other 855R beacons, the green screw-in base is compatible with Rockwell signaling accessories and is designed to withstand typical industrial environments.
