LOGIC_DRIVES_SCR_

Published:2009/7/14 1:32:00 Author:May | From:SeekIC

Uses light-activated SCR in H74C1 optoisolator to trigger larger SCR for controlling loads up to 3000 W through bridge diodes, When logic input goes low (to ground), load is energized. Limit for inductive loads is 8 A or about 1000 W if using 25-A SCR.-D. D.Mickle, Practical Computer Projects, 73 Magazine, Jan. 1978, p 92-93.
