Allen-Bradley 800T-QB24R NSNBC01 Servo Drive Module

Allen-Bradley 800T-QB24R is a compact 30 mm red illuminated pushbutton from the 800T operator interface family, designed for clear operator signaling on control panels. It operates on 24 V AC/DC and provides illumination to indicate the button’s status in harsh industrial environments. The 800T family offers rugged enclosure options with Type 4/13-rated protection, enabling use in wet, dusty, and washdown areas. This model is intended for panel mounting in standard 30 mm openings and can be paired with compatible 800T contact blocks to create a complete signaling station. In typical manufacturing, packaging, and process-line applications, red illumination is used to denote stop, fault, or critical-status signals, ensuring quick recognition by operators. The 800T line is designed to integrate with Allen-Bradley control systems and PLCs, supporting straightforward wiring and consistent performance across modular pushbutton assemblies. For technicians, key considerations when specifying this part include confirming 24 V supply compatibility, matching the color and illumination requirement, and verifying the enclosure rating for the intended environment.
