Allen-Bradley 800HC-QRH24B Industrial Servo Drive

Allen-Bradley 800HC-QR24B is a 30 mm pilot-light indicator from the 800H family designed for control-panel installations where a rugged, visible signal is required. It accepts 24V AC/DC on its illumination module, powering an incandescent lamp to emit a blue indicator light through a round Fresnal-cap lens. The device mounts in a 30.5 mm hole and uses screw-terminal connections with finger-safe terminations for safe wiring. It supports full-voltage illumination and is compatible with NEMA 1, 4, 4X, 12, and 13 enclosures; it also carries a Class I, Division 2 hazardous location rating, making it suitable for some hazardous environments. Wiring on the illumination circuit uses 14-18 AWG conductors, secured with a 6-8 in-lb tightening torque. Operating conditions include -25 °C ambient and 50% humidity, with storage down to -40 °C; the unit is designed for broad market compliance, carrying certifications such as ABS, CCC, CE, CSA, EAC, GOST, and UL. As a compact status indicator, it signals machine state, fault conditions, or process steps in control panels without adding significant panel depth. Note: this model is a pilot-light accessory, not a servo drive, and is intended for signaling rather than motion control.
