The Macromatic TD-71622 is an Off Delay Time Delay Relay. This 11 pin plug-in relay has an input voltage of 120V AC/DC with an output of 10A DPDT. It has a time range of 0.05 sec to 999 hours. The unit has one pushbutton thumbwheel that chooses one of seven time ranges, while three other thumbwheels digitally set the precise time delay within that range. The red LED indicates the current status of the timing mode and time out conditions. The TD71622 uses an 11 pin 70170-D octal socket. Note: Image is an approximation. Actual part may differ.

With the Off Delay function, the relay energizes once the trigger is introduced. The time delay only starts once the trigger is taken out. After the time delay ends, the relay de-energizes. Re-introducing the trigger before the time delay finishes resets it, preventing the relay from de-energizing. The input voltage needs to be in place for the trigger to be successfully applied.
