Allen-Bradley 855E-24TL6 LED Indicator Light

Allen‑Bradley 855E-24TL6 is a 50 mm Control Tower Stack Light module from Rockwell Automation that uses a blue steady-state LED and is designed for socket-mount installation with 24 V AC/DC full voltage. The TL designation identifies a steady socket-mount LED within the 855E family, compatible with standard 50 mm stack-light bases to provide a continuous blue indicator on industrial equipment, conveyors, or control panels. This module delivers a compact, bright signal suitable for signaling a specific machine condition at a glance, with a blue LED that remains illuminated under typical operating conditions when wired to a 24 V system, offering reliable visibility in factory environments. Ideal applications include status signaling on automated production lines, packaging setups, and process-control panels where quick, unambiguous visual feedback is required; the blue indicator helps operators distinguish a particular state without audible or other signals.
