Allen-Bradley 855E-24TL8 is a 50 mm control tower stack-light module with a yellow lens and a steady LED lamp, designed for socket-mount installation in 855E/855T signaling towers. It operates from 24V AC/DC full voltage, compatible with standard 24V control circuits without an external transformer. This Rockwell Automation part—listed as 855E-24TL8—is manufactured in Austria and serves as the yellow status indicator within a 50 mm stack-light assembly, providing continuous illumination to convey machine state at a glance.
