Allen-Bradley 800T-PST16B Pilot Light Indicator

Allen-Bradley 800T-PST16B Pilot Light Indicator is a blue 18 mm small pilot light designed for 800T pushbutton stations. It uses an incandescent lamp and is rated for 120V AC, 50/60 Hz, with a transformer-type input option (or dual-input configuration) and a Push-to-Test (PST) feature that allows quick lamp testing without energizing the whole control circuit. This indicator provides a compact, panel-mount lighting solution that fits standard 18 mm operator footprints, making it suitable for signaling machine status in control panels, motor control centers, conveyors, and other industrial automation gear. The blue lens offers clear, high-contrast visibility in busy environments, helping operators quickly discern status such as running, fault, or ready conditions. As part of the 800T family, the PST16B variant is specifically configured for transformer-type inputs and PST operation, enabling reliable illumination in a variety of installations that require 120V AC power. The unit’s rugged panel-mount design is intended for standard industrial applications where a small, dependable indicator communicates a single, unambiguous status at a glance.
