Optoisolators, also known as opto-electronic isolators, are optically-coupled, solid-state devices which allow signals to pass from one part of an electronic system to another without any physical connection, thus providing electrical isolation between the elements of the system.

Transistor, photovoltaic output optoisolators, such as ELD211-V, are equipped with a photovoltaic diode as the light-sensitive element. This element senses a change in current by detecting a light signal emitted from a light source. The output side is built with a transistor that is enabled and disabled depending on the state of the input and the detection of a light signal. Transistor, photovoltaic output optoisolators are easy to use and extremely reliable, making them suitable for a variety of applications.

The main benefit of using ELD211-V optoisolators is their ability to electrically isolate the input and output circuits. This helps to reduce electrical noise, prevent the input from being damaged by high voltage, and improve system stability. ELD211-V optoisolators also offer fast response time and high isolation voltage, making them ideal for high-precision applications.

The primary application of ELD211-V optoisolators is for switching and interface control. They are used in a variety of systems such as industrial control equipment, automotive control modules, home appliances, medical devices, and automated obstacle avoidance systems. ELD211-V optoisolators are also commonly used in process control systems to protect sensitive components and circuits from electromagnetic interference or industrial environmental conditions.

The working principle of the ELD211-V optoisolator is relatively simple. It consists of a photodiode and a phototransistor, which are arranged as shown in the figure below. The photodiode is sensitive to light, and when a control signal is present, it emits a light pulse which is detected by the phototransistor. The transistor is then enabled or disabled depending on the state of the input signal.

The ELD211-V optoisolator has a maximum input voltage of 25 volts DC, and a maximum current of 400 mA. It also has a maximum turns ratio of 10:1, and its isolation resistance is greater than 1000 Megaohms. The ELD211-V optoisolator is also highly efficient and it has a low power dissipation rating.

ELD211-V optoisolators are designed for use in industrial and commercial applications, and they provide a highly reliable way to electrically isolate the input and output circuits. They offer fast response time and high isolation voltage, and their low power dissipation rating makes them ideal for a variety of applications. This makes them an ideal choice for anyone looking for a reliable and efficient optoisolator.
