Allen-Bradley 855T-G10BC6 Control Tower Stack Light

The Allen-Bradley 855T-G10BC6 Control Tower Stack Light is a modular signaling tower used on industrial equipment to convey machine status with stacked lights. Belonging to the 855T Control Tower Stack Light family, this model is designed to accept multiple light modules in a single tower—up to five modules on one base—so you can represent different states with separate colors. It is designed for flexible mounting on a range of bases, including surface-mount bases and pole or tube mounting options, enabling installation on diverse enclosures and frames. Color-coded light modules provide rapid visual cues, and many 855T configurations support combinations of light and sound modules and optional network bases for integrated control. Typical applications include signaling run, stop, warning, fault, or process-ready conditions on manufacturing lines, packaging equipment, conveyors, robotics, and other automated processes, helping operators quickly interpret equipment status at a glance. This configuration within the 855T family is designed to integrate with standard Allen-Bradley signaling practices, ensuring consistent interface with related control hardware and panel layouts.
