Allen-Bradley 854J-10GL5 LED Indicator Light Module

Allen-Bradley 854J-10GL5 is a 40 mm stack-light light module with a flashing amber LED, designed for use in Rockwell's ControlTower signaling assemblies to provide a rapid visual alert on automated equipment. This 854J light module operates from 120V AC and delivers an amber flash with an estimated light intensity of 2391 millicandelas at 120V, ensuring high visibility in cabinets and work areas. As a GL (flashing LED) module, it tolerates leakage currents up to 3 mA from solid-state outputs without triggering unintended activation, which helps prevent nuisance signaling in systems with mixed output types. Common applications include machine-status indication on manufacturing lines, packaging equipment, and other industrial controls that employ Allen-Bradley 40 mm stack-light configurations for clear, immediate status signaling.
