Allen-Bradley 855BL-N24RH5 LED Indicator Light

Allen-Bradley 855BL-N24RH5 LED Indicator Light is a blue LED signaling beacon designed for industrial control panels. As part of Rockwell Automation's 855 signaling family, the N24 suffix indicates 24V operation (AC/DC), and RH5 denotes the specific blue LED variant in this line. It supports panel- or surface-mount installations and provides a clear visual indication for machine status, alarms, or process conditions in rugged environments. The unit features a polycarbonate lens and housing, and, when used with the correct base, carries the IP65 protection rating for outdoor or harsh indoor spaces. The 855BL series is documented for operation across a wide -25 to +60 °C temperature range, making it suitable for factory floors and warehouses. Typical applications include control panels, operator consoles, and signaling points in manufacturing environments where a distinct blue indicator is used to communicate status or alerts.
