Allen-Bradley 855E-24FN5 Amber Stack Light 24V AC DC

Allen-Bradley 855E-24FN5 is a 50 mm amber light module designed for Rockwell Automation’s 855E/855T Control Tower Stack Lights. This 24 V AC/DC full-voltage unit uses a flashing incandescent lamp module (FN5) to deliver a bright amber signal, making it ideal for visible status indications on control panels and automated equipment. The module's amber lens and 50 mm face diameter align with standard 50 mm signaling frames, enabling straightforward installation into existing stack-light assemblies. As part of the 855E family, the 855E-24FN5 is intended to be paired with corresponding light modules and bases to create multi-color status indicators on a single stack, supporting common signaling patterns such as run/fault/maintenance states on manufacturing lines. Typical applications include signaling machine readiness, faults, and process state in industrial automation environments, with compatibility across 24V AC/DC control circuits and Rockwell's documented signaling codes for amber color (code 5) and flashing incandescent illumination.
