MICROCOMPUTER_TO_TRIAC_INTERFACE

Published:2009/6/16 23:16:00 Author:May | From:SeekIC

A microcomputer-to-triac interface uses a phototriac optoisolator to let safety-isolated logic sig-nals directly control high-power loads. Depending on the input waveforms and the load, this circuit can be used in either an on/off switch or a proportional phase control. A low input powers the lamp.
