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** 

On-Delay, Off-Delay and Interval. 

## **Timing Specifications** 

**Timing Ranges:** 6 to 180 cycles; 0.1 to 3 / 0.1 to 10 / 0.33 to 10 / 1 to 30 / 4 to 120 sec.; 0.33 to 10 / 1 to 30 / 2 to 60 min.; 0.33 to 10 hr. (All are +5%, –0% of maximum values). 

**Timing Adjustment:** Knob or fixed time (internal fixed resistor) – all models; customer supplied external potentiometer or resistor – On-Delay and Interval models only. 

**Accuracy: Repeat Accuracy:** ± 0.5% ± 0.004 sec. 

**Overall Accuracy:** ± 2% max. 

## **Input Data @ 25** ° **C** 

**Voltage:** See Ordering Information section for details. **Power Requirement:** 3W, max. 

**Transient Protection:** Non-repetitive transients of the following magnitudes will not cause spurious operation of affect function and accuracy.
