Allen-Bradley 22DJ9-4000 Time Delay Control Module

Allen-Bradley 22DJ9-4000 Time Delay Control Module is a Series 4000 LED time-delay plug-in control module designed to work with Allen-Bradley Photoswitch photoelectric sensors to insert controlled delays in outputs. As model 22DJ9-4000, it belongs to the 22DJ9 family and provides configurable ON-delay and/or OFF-delay timing to regulate outputs based on sensor input; it uses a plug-in format for quick installation in compatible bases and sensor assemblies. The Series 4000 family is documented by Rockwell as LED time-delay plug-in modules with models 4000 and 4001; installation instructions describe adjustable timing for these modules to tailor response to sensing conditions and the modules typically include an LED indicator to show status. This module is commonly used to prevent false triggers by delaying output activation after a sensor detects a target or to ensure clean de-energization after the input condition ends. The official Rockwell product page confirms the 22DJ9-4000 identity and positions it within Allen-Bradley’s plug-in time-delay lineup, while distributor listings place it in the Photoswitch/Photoelectric sensor family of devices.
