WORKING:
The MOC3021 was designed for interfacing between electronic controls and high power TRIAC to control loads for (AC Votage) operations.
A small pulse (Clock pulse with 5 V range) is applied to its input that is pin 1 and pin 2.
The light produced by this LED activates the TRIAC and that time power is switched ON.
Mainly it is used to maintain isolation between low power circuit to high power circuits (that is a 5v pulse controls 3 phase load volts).
APPLICATION:
1. As Triac driver.
2. Motor drive.
3. Consumer appliances.
4. Like solid state relay.
5. 230V solenoid valve operation.
6. Lamp dimmer.
