Allen-Bradley 855E-10DN4 Panel Mount Indicator Light

Allen-Bradley 855E-10DN4 is a 50 mm Control Tower Stack Light module intended for panel mounting, providing a visible status indicator for industrial equipment. The DN4 suffix identifies a steady incandescent light, and this red-lensed variant operates at 120 VAC for full-voltage signaling in control panels. As part of the 855E family, the unit carries safety and compliance certifications common to Rockwell Automation signaling products, including UL 508 and CSA listings, with CE marking for international use. Designed for on-panel signaling in automation systems, it serves as a compact, rugged indicator for machine status, faults, or process conditions in control rooms or at machines.
