Allen-Bradley 855E-10BR5 Control Tower Stack Light

Allen-Bradley 855E-10BR5 Control Tower Stack Light is a 50 mm signaling light module designed to mount on Allen-Bradley 855E Control Tower stacks for clear, visible status indication in industrial automation. This 120 V AC full‑voltage module uses a BR (Strobec) lamp module with an amber lens to deliver a bright, attention‑getting strobe for machine‑state signaling across a control tower. The unit is 50 mm in diameter and carries the unique product identifier 855E-10BR5, making it compatible with the 50 mm Control Tower lighting family. In the 855E signaling family, the BR designation denotes a Strobec lamp configuration with amber coloration, suited for conspicuous status alerts. Note that Rockwell has scheduled the 50 mm Light Module in this series for discontinuation after December 31, 2025, with recommended replacements such as the 855E-10GL5 (Green LED) variant or other 855E signaling options depending on color and lamp type. Typical applications include indicating run, fault, stop, or other machine states on automation panels and production lines where a high‑contrast amber indicator improves visibility and response times.
