Optoisolators, such as the ELD213 (TA) products, are designed to protect circuitry by providing electrical isolation between two circuits. This type of opto-coupler is mostly used in communication systems, motor drives, servo control, and other industrial applications that require isolated outputs or for controlling of high voltage loads. The ELD213 (TA) opto-coupler consists of a phototransistor, photovoltaic cell, and an LED. The photovoltaic cell receives light from the LED and converts it into a proportional current which is then amplified by the phototransistor to provide an output signal.

The ELD213 (TA) opto-coupler is ideal for transfer of signals between different circuits, providing complete electrical isolation, while also transmitting the signal with minimal signal distortion. The device operates by allowing light to be transferred from an LED to a photovoltaic cell. This photovoltaic cell then converts the light into a current which is proportional to the intensity of the light. This current is then used to activate an optical transistor allowing the current to be amplified to provide a proportional output voltage.

The ELD213 (TA) provides electrical isolation between the input signal and the output by using the light transfer method instead of direct electrical connection. This isolation is important to protect both the input and the output circuits from damage. The ability to transfer signals with minimal distortion is especially important in industrial applications such as servo control where accuracy is critical.

The ELD213 (TA) is typically used in applications where the input voltage is as low as 0.5V and the output voltage is 500V. Since the input and output voltages can be quite different, isolation is important to protect both the input and output circuits from damage. The ELD213 (TA) is also designed to handle a large dynamic range of input signals and has a fast response time. It also has a low power consumption.

The ELD213 (TA) is a popular opto-coupler that is used in many different applications due to its ability to provide electrical isolation and its flexibility. It is frequently used in communication systems, motor drives, servo control, and other industrial applications that require isolated outputs or for controlling of high voltage loads.
