Universal Voltage Input Buffer

 

 

The universal input buffer will take any voltage from 10.6 to 265 VAC/DC and actuate any NCC timer requiring a start switch to initiate a timing cycle.

Operating Logic: Upon application of Input voltage, the output becomes an effective contact closure (within 50 mS). Upon removal of input voltage, the output becomes an effective open circuit (within 50 mS).
