An opto isolator is an electronic device that prevents high voltages from components in one side of a circuit from damaging or interfering with components on the other side of the same circuit.

An opto isolator is an electronic device that prevents high voltages from components in one side of a circuit from damaging or interfering with components on the other side of the same circuit.

to prevent the high voltages The main purpose of an opto-isolator is "to prevent high voltages or rapidly changing voltages on one side of the circuit from damaging components or distorting transmissions on the other side."[2] Commercially available opto-isolators withstand input-to-output voltages up to 10 kV[3] and voltage transients with speeds up to 10 kV/μs.[4]

The MOC3041 is an opto-isolator, also known as opto-coupler, the function of opto-coupler is to provide electrical isolation between two different circuits, there are several types of opto-couplers, which have an LED and one another switching device, i.e. transistor, diac or triac, The MOC3041 contains one LED and one Triac with a zero crossing detector at its gate input, so it can be used to provide triggering pulses to the high power triac, used for controlling power to the AC Load. For more details, see the datasheet of MOC3041.

Edison-Opto was created in 2001.
