Users should thoroughly review the technical data before selecting a product part number. It is recommended that user also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application. 

## **Timing Mode** 

**Delay on operate** – Delay period begins when input voltage is applied.  At the end of the delay period, the relay will operate and will not release until input voltage is removed.  Reset occurs when input voltage is reapplied.
