KRD3 SERIES  
Description  
The KRD3 Series measures only 2 in. (50.8 mm) square.Its  
solid-state timing circuit provides excellent repeat accuracy and  
stability. Encapsulation protects against shock, vibration, and  
humidity. The KRD3 Series is a cost effective approach for OEM  
applications that require small size, isolation, reliability, and  
long life.  
Operation (Recycling Flasher - ONTime First)  
Upon application of input voltage, the output energizes and  
theT1 ON time begins. At the end of the ON time, the output  
de-energizes and theT2 OFF time begins. At the end of the  
OFF time, the output energizes and the cycle repeats as long as  
input voltage is applied.  
Reset: Removing input voltage resets the output and time  
delays, and returns the sequence toT1 ON time.
