Allen-Bradley 22DJ9-4000

The Allen-Bradley 22DJ9-4000 photoelectric time delay control module is designed to provide efficient management of on-off and off-on delays, making it essential for controlling Photoswitch devices featuring pulsed LEDs while effectively minimizing ambient light interference. With its swift response times, this versatile module accommodates various configurations including reflected beam, transmitted beam control, and reflex scanning modes, thereby enhancing its usability in presence sensing applications. Its rugged construction is compatible with Series 3000 and Series 4000 control bases and features synchronized detection circuits, adaptable relay or solid-state logic outputs, and selectable modes for light or dark energized operation. Operating reliably across a temperature range from -40 to 57 degrees Celsius, the module guarantees consistent performance with minimal fluctuation in time delay despite changes in voltage or temperature.
