Allen-Bradley 855E-24TL8 LED Stack Light Assembly

Allen-Bradley 855E-24TL8 is a 50 mm Control Tower Stack Light module designed for panel mounting on industrial equipment. This socket-mount LED lamp module features a steady yellow illumination and operates from a 24 V AC/DC supply (full-voltage LED option within the 24 V TL LED family). As part of Rockwell Automation's 855E signaling lineup, it provides unambiguous, continuous signaling for machine status, faults, or warnings in manufacturing environments. The compact 50 mm footprint fits standard control panel cutouts, enabling easy integration with compatible 855E bases and accessories to form a complete signaling tower. The LED lamp module (type TL) is designed for quick replacement in the field, reducing downtime when a lamp needs servicing. Suitable for use on production lines, packaging stations, and process-control applications, this yellow LED indicator helps operators quickly assess equipment state at a glance, even in bright environments. With 24 V input compatibility, the unit wires into common PLC power supplies and control circuits without requiring additional transformers, simplifying integration with existing control architectures.
