Allen-Bradley 800H-QPT24R Push-To-Test Pilot Light

Allen-Bradley 800H-QPT24R is a 30 mm red pilot light with a Push-To-Test function, part of the rugged 800H family designed for industrial control panels. This 24 V AC/DC device is intended for full-voltage operation and is rated for Type 7/9 hazardous locations, making it suitable for demanding environments where visibility and reliability are critical. It mounts in standard 30 mm 800H frames and provides immediate visual indication to signal machine status—such as power, stop, or fault conditions—in automation equipment. The integrated Push-To-Test feature enables lamp verification without energizing the downstream circuit, streamlining maintenance and commissioning. Common applications include signaling and status indication in control circuits, safety interlocks, and process lines, especially in environments where a red indicator is conventional for hazard or stop conditions. The 800H line’s robust construction and compatibility with other 800H operators and accessories support straightforward panel wiring, replacement, and expansion as system needs grow.
