Allen-Bradley 855T-B24TL3 Green Flashing Stack Light

The Allen-Bradley 855T-B24TL3 Green Stack Light is a 70 mm control-tower indicator module from the 855T family, engineered to mount on standard 70 mm bases and interoperate with other color modules to form a scalable status tower for industrial equipment. This 24V AC/DC TL3 variant uses a steady green LED illumination behind a green lens to convey a healthy operating condition, enabling clear visibility across shop floors, production lines, and automated cells. While designed for rugged environments, distributor listings commonly note NEMA 4/4X/13 compatibility for this 855T module, reflecting its suitability for washdown and dusty settings in harsh industrial environments. Typical applications include signaling run, in-progress, or status health on conveyors, packaging lines, robotic cells, and other automated machinery, where a bright green indicator helps operators monitor line activity and coordinate downstream processes as part of a broader Visual Workcell strategy. As part of the Allen-Bradley Control Tower stack-light ecosystem, the 855T-B24TL3 offers straightforward wiring, compatibility with related 855T accessories, and a compact footprint that complements standard machine-control enclosures.
