Microcomputer-To-Triac Interface Circuit

  
A microcomputer-to-triac interface uses a phototriac optoisolator to Jet safety-isolated logic signals 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.
