Allen-Bradley 800H-PP16A Illuminated Pilot Light

Allen-Bradley 800H-PP16A Illuminated Pilot Light is a heavy‑duty, hazardous-location indicator module from the 800H family. It provides amber illumination through an incandescent lamp and includes a built‑in transformer (XFMR) to operate from a 120 VAC supply. Rated for Type 7/9 hazardous locations, this variant is designed for panel mounting with a standard barrel length and compatibility with Allen‑Bradley 800H pushbutton bases. The unit is specified for 120 V AC at 50/60 Hz and uses an incandescent lamp source, delivering clear, high‑visibility status signaling in demanding industrial environments. Typical applications include machine status indication, control circuits, and safety interlocks in petrochemical plants, refineries, and other locations where electrical equipment may encounter hazardous atmospheres. By integrating the transformer, the 800H-PP16A reduces additional wiring and simplifies installation within control panels, while the amber color provides immediate, color‑coded indication for operator awareness. The rugged construction and compliance with hazardous-location standards make it suitable for heavy‑duty automation panels where reliability and clear signaling are essential.
