What is Opto-Isolator?
Opto-Isolator is an electronic device that uses light to send signals between parts of the circuit. This allows the circuit elements to communicate without electrical connection. The advantage of this insulation is that it prevents voltage spikes affecting multiple circuits. It also helps to reduce the noise and interference of audio and video devices by preventing the flow of electric current where it is not asked. Most opto-insulators are very cheap and cost less than $ 1.
Opto-isolator operation is a relatively basic process. When an electronic signal reaches opto-isolate, this signal is converted into light. The light is then transmitted to the receiver. After receiving the signal, the electronic signal is converted back to the electronic signal.
There are two basic types of opto-insulators that have their own use. Digital Opto-Isolator changes the status of its output to match the input status. It should be used in bit or pulsates the necessary output. Analog insulator reproduces the input using an analog signal. This type of Opto-Isolershould be used when the amount of signal is a key factor.
Average Opto-Isolator consists of three basic parts. The solid case protects against the leakage of outer light into the insulator. The signal is sent by the LED emitting diode (LED) or other small light source and the signal receives a photo -integral part. The most common light receivers are photodiodes and phototransistors. From the outside, Opto-Isolator looks like a transistor that has connected other lines.
In many cases, the term "Opto-clipper" is used interchangeably with "Opto-Isolator", but there is a difference between the two devices. Both transmit the information between the elements of the circuit and allow the elements to remain isolated. The difference comes from the potential voltage of circuits.Otto-isolator is designed for use with systems with potential voltages between 5,000 and 50,000 volts, and Opto-binds are designed only for use in systems where the potential voltage is less than 5,000Volts. Using the wrong device can cause system failure.
moisture can also cause major problems for opto-insulators. If there is too much moisture in the air, electricity could arch and destroy electronic insulation. Similar problems may be caused by barometric pressure and air pollution can cause similar problems. The best way to prevent this problem is to maintain electronics that use opto-insulators in the controlled climate area.
