Zero-Cross Sensor, Programmable Firing, Triac Output

ZCD-220V03W-IFS is a 110V/220V RMS AC voltage zero crossing sensor where you can configure multiple signal features. It detects the zero-crossing point where the AC voltage applied as input does not make a potential difference and fire the Triac at its output at the determined firing start point. Firing duration is also one of the adjustable signal features.
