Allen-Bradley 855E-12DN4 Beacon Light 12 Volt DC

The Allen-Bradley 855E-12DN4 is a 50 mm control tower stack light that provides a steady red signal from a 12 V AC/DC incandescent lamp. The red lens and 50 mm light module mount to panels or machine enclosures for visible status indication in automation and control applications. Key specifications include 12V AC/DC full‑voltage operation, a rated 7 W incandescent lamp, and a steady illumination mode; the unit is designed as a single, mountable light module within the 855E stack-light family. Typical applications include panel‑mounted signaling on control consoles, conveyors, automated lines, and other equipment where a clear, continuous red beacon is needed to indicate a running, stopped, or fault condition. The 855E‑12DN4 aligns with the 855E family’s rugged signaling standards, offering features common to 50 mm stack lights and suitability for indoor and outdoor use under UL Type 4/4X/13 and IP65-rated environments.
