Allen-Bradley 855D-T00SC20B24Y3Y5Y4C1 Tower Light

Allen-Bradley 855D-T00SC20B24Y3Y5Y4C1 is a 30 mm Compact Tower Light engineered for direct-mount installation on industrial equipment. Using a metric M20 threaded tube, it accepts direct-mount light modules and operates from 24 V AC/DC power. The housing combines a yellow jacket with a black base and ships with a 2 m stranded SC20 cable for straightforward wiring. This non-modular preassembled unit provides three steady LED indicators—Green, Amber, and Red—without an integrated sound module or network option, delivering clear, immediate visual status signals. Ideal for signaling machine state on production lines, packaging equipment, and automation systems, it offers a compact form factor that fits tight control panels while meeting standard signaling conventions. As part of Rockwell Automation’s 855D/855F compact control tower family, it supports reliable, low-maintenance operation in demanding industrial environments.
