Allen-Bradley 855E-24DN5 B1 Industrial Controller

Allen-Bradley 855E-24DN5 is a 50 mm control tower light module in Rockwell Automation's 855E signaling family, delivering a steady amber indicator via an incandescent lamp and designed for 24 VAC or 24 VDC power. This 50 mm lens module threads into a standard 50 mm tower frame to form part of a multi-color signaling stack on Allen-Bradley 855E Control Tower assemblies, enabling operators to quickly gauge machine status on the shop floor. Key specs include a 24-volt supply (AC or DC), incandescent lamp type, amber color, and a 50 mm diameter lens, with compatibility to common industrial signaling standards and safety certifications such as UL 508 and CSA C22.2 No. 14, plus EN/IEC 60947-1/60947-5-1 as applicable to signaling components. Typical applications include signaling normal operation, process progression, or machine readiness in PLC-controlled production lines, packaging equipment, and automated manufacturing cells, where a single amber steady light communicates a specific state alongside other color modules. When paired with other 855E modules, it contributes to a clear, color-coded signaling tower that can be wired into standard control circuits and PLC outputs for straightforward status indication without opening panels. The 855E-24DN5’s compact 50 mm footprint and fixed, steady illumination make it a reliable replacement or upgrade for existing 855E towers where persistent amber signaling is required.
