Allen-Bradley 855T-B24DN5 Incandescent Indicator Light

The Allen-Bradley 855T-B24DN5 is a 70 mm control-tower stack light with a Black housing that delivers a steady amber signal from a built-in incandescent lamp. This 24 V AC/DC full‑voltage module is designed for panel-mounted signaling and comes with the bulb included, making it a ready-to-install status indicator for machines, conveyors, and automated equipment. In the 855T family, the DN5 designation identifies a steady incandescent amber light; the unit offers a lamp life rating around 7,000 hours for incandescent modules and is compatible with other 855T stack-light modules to form multi‑color signaling towers. The housing is black, and the unit carries a NEMA rating of 4/4X/13, supporting installation in a variety of industrial environments where enclosure protection is required. With its 70 mm diameter footprint, this amber indicator is suitable for control panels and machine interfaces where a clear, continuous amber state communicates conditions such as standby, caution, or general status without flashing or color transitions.
