Optoisolators are components used to pass electrical signals between circuits which are electrically isolated from one another. They create an “opto-electronic barrier” to prevent noise from one circuit or component from adversely affecting another. OPI1264A is a specific type of optoisolator that offers an efficient and reliable method of passing signals between circuits. This article will discuss the application field and working principle of the OPI1264A.

The OPI1264A is an optoisolator designed to transmit electrical signals over an air gap between circuits or over a printed circuit board while providing high isolation voltage between inputs and outputs. It combines a low-power input LED with a bi-directional photocoupler output which provides safety insulation and prevents ground loops and electromagnetic interference. This makes the OPI1264A ideal for applications such as current sensing, switching relays, motor controls, industrial process controls, AC or DC motor control, temperature control, light control, power supply control, analog signal isolation, and logic signal isolation.

The OPI1264A optoisolator is based on a principle of photocoupling. It uses a photoemitter and photo-sensitive device to transmit signals between circuits. The photoemitter in the OPI1264A is a light-emitting diode (LED). The LED is connected to an input voltage source and emits a small amount of light. This light is detected by the photo-sensitive device, which is typically a photovoltaic output transistor. The photovoltaic output transistor converts the light from the LED into an electrical current or voltage that can be used by the output circuit. The electrical signal from the photo-sensitive device is then amplified and used to control the output device.

The OPI1264A optoisolator is a highly reliable device that provides excellent electrical isolation. It exhibits fast switching speed, low power consumption, and wide temperature range. It is UL rated with a maximum isolation leakage rate of 10mA and a maximum isolation voltage rating of 600V. The OPI1264A is also available in a variety of package sizes and is RoHS Compliant.

OPI1264A optoisolator is widely used in industrial application due to its low cost, reliable performance, and wide temperature range. It is most commonly used for switching relays, motor control applications, temperature control, and light control. This makes the OPI1264A an ideal solution for industrial applications and process control where reliable and efficient signal transmission is required.

In conclusion, the OPI1264A is ideal for industrial applications due to its low cost, high reliability, and wide temperature range. It is based on a principle of photocoupling, using a light-emitting diode (LED) and photovoltaic output transistor to transmit signals between circuits. Its features include fast switching speed, low power consumption, and high isolation voltage rating of 600V. The OPI1264A is also UL rated and RoHS Compliant, making it an excellent choice for industrial applications.
