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 Modes** 

**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. 

## **Initial Dielectric Strength** 

**Between Open Contacts:** 500V rms, 60 Hz. **Between All Other Conductors:** 500V rms, 60 Hz.

## **Input Data @ 25** ° **C** 

**Delay on release** – Input voltage must be applied continuously to operate the internal relay.  When control Input is applied, the relay energizes. When control input is removed, timing begins.  When timing is complete, the relay will de-energize.  Time may be reset to zero during timing by reapplying control input.

- If control input is applied when supply input is applied, relay will immediately energize.  A 50 millisecond minimum control pulse is required. 

-  Note** Input polarity for DC operation.  For most reliable operation on AC, connect high side to “+” and low side to “–”.
