The Allen Bradley 22DJ9-4001 is a time-delay LED control module specifically designed for use with Photoswitch photoelectric sensors, enabling precise control of lighting response based on detection conditions. It operates in two selectable modes: “dark energized” (D) mode and “light energized” (L) mode, with mode selection accomplished by adjusting the switch to the “DK” (dark) or “LT” (light) position. Engineered for accuracy and flexibility, the 22DJ9-4001 ensures dependable photoelectric control in automation and sensing applications. In North America, Europe, Asia, and worldwide installations, this control module could potentially be utilized in sensor systems requiring adjustable time-delay functions and mode-selectable illumination response.
