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.  
Tim ing Mode  
Input Data @ 25°C  
One Shot (Latching Interval).  
Voltage:(±10%): 12 VAC/VDC, 24VAC/VDC, 120 VAC/VDC.  
Pow er Requirem ent: 4W, with rated load.  
Transient Protection: Non-repetitive transients of the following magni-  
tudes will not cause spurious operation of affect function and accuracy.  
Tim ing Specifications  
Tim ing Ranges: 0.5 to 10 / 3 to 60 sec.; 0.5 to 10 / 3 to 60 min.  
Tim ing Adjustm ent: External resistor or potentiometer. An external  
resistance of 1 megohm is required to obtain the  
maximum time for all ranges. To determine the actual  
resistance needed to obtain the required time delay,  
use the following formula:
