Allen-Bradley 855BM-S24RH5 Indicator Light

Allen-Bradley 855BM-S24RH5 is a 120 mm blue indicator beacon from Rockwell Automation’s signaling line, designed for panel-mount visibility on industrial equipment. This beacon serves as a clear status indicator for machines and control panels, displaying a bright blue signal that can be observed from across a work area to communicate operating states, alarms, or process conditions. The 120 mm housing and blue lens are specified for use in demanding environments where quick visual feedback is essential, helping operators and maintenance staff assess status at a glance. The S24RH5 suffix in the model designation identifies the 24V signaling variant within the 855BM family, aligning with common low-voltage control circuits found in many manufacturing setups. Ideal applications include conveyor and packaging lines, presses, and other automated equipment where an immediate, unmistakable beacon is required to indicate conditions such as standby, running, fault, or alert states. As a longstanding Allen-Bradley signaling solution, the 855BM-S24RH5 is a purpose-built visual indicator that integrates into a broader signaling strategy on industrial equipment, providing durable, easy-to-read indication in busy production environments.
