Allen-Bradley 800T-PSD16 is an 18 mm small pilot light designed for panel-mount status indication in industrial control circuits. It uses a transformer (or dual-input) power module and an incandescent lamp, rated for 120V AC at 50/60 Hz, making it compatible with standard control-system supplies. The Dual Input designation refers to the power-module option within the Rockwell 800T family that supports either transformer-fed or dual-input wiring, ideal for indicator lighting in push-button assemblies and control panels. This 800T device is commonly used to signal machine states, process status, or alarms in automation equipment.
