Allen-Bradley 855E-24TL3 Stack Light Tower

Allen-Bradley 855E-24TL3 is a 50 mm Control Tower Stack Light lamp module for 855E stack-light assemblies. It provides a steady green LED indication through a socket-mounted LED module and operates from 24 V AC/DC full voltage. The TL3 suffix identifies the green illumination color; the family also includes 855E-24TL4 (red) and 855E-24TL8 (yellow) variants for color-moded signaling. This module is designed to be inserted into a 50 mm stack-light tower to convey machine status on automation equipment, production lines, conveyors, and packaging cells. By matching the proper color to your signaling scheme, it helps operators quickly interpret state information such as running, stopped, or fault conditions at a glance. Compatible with standard 855E control-tower configurations, the lamp module integrates into the tower with straightforward wiring and provides a robust, color-coded visual indicator for industrial environments.
