Allen-Bradley 855T-B10BR8 Stack Light Control Tower

Allen-Bradley 855T-B10BR8 Stack Light Control Tower is a 70 mm signaling beacon designed for mounting on automated equipment to provide a clear yellow, 120 V AC strobe indication. This model is part of the Bulletin 855T Control Tower Stack Lights family and uses a Strobe module (code BR) within the 855T line, ensuring compatibility with standard 70 mm bases for modular stacking. The unit is specified for 120 VAC operation and delivers a high-visibility flash suitable for operator attention on busy production floors, with the yellow color commonly used to indicate caution or a particular status in multi-light towers. As a 855T module, it can be combined with other color modules to form a multi-light stack, enabling quick at-a-glance signaling of different machine states across the line. Typical applications include conveying machine status, fault indication, or process alarms in manufacturing, packaging, and material-handling environments where rapid recognition from a distance is critical.
