Optoisolators are electric devices used for isolating two circuits from each other while allowing signals to pass between them. An optoisolator uses a light-emitting diode (LED) and a photovoltaic cell (PV cell) in conjunction to transmit signals between circuits of different nature. Photovoltaic output optoisolators, like the EL205(TA)-V, are particularly useful for transmitting signals in situations where a very low voltage or current is too small to be detected.

The EL205(TA)-V is a horizontal, slotted-photo transistor with a built-in dual resistor. It is a type of optocoupler that provides electrical isolation between two circuits, and features high perforations resistance. This device is often used to control LEDs or lamps in relays, and it features an exceptional current to voltage (I/V) conversion ratio. The EL205(TA)-V optoisolator has a photo-sensitive surface that is coated with a material that generates an electrical current when illuminated.

In terms of its application field, the EL205(TA)-V optoisolator is suitable for use in industrial equipment and high-precision optical instruments. It can be used in a variety of devices, such as traffic signal controllers, smoke detectors, and power supplies.

The working principle of the EL205(TA)-V optoisolator is based on the relationship between the electrical current generated by the LED when illuminated, and the voltage generated by the photosensitive surface of the PV cell. When a current is applied to the LED, it emits a light, which is then detected by the PV cell. The PV cell then converts the light energy into an electrical current. This current then passes to the output, and can be used to switch on and off relays or other devices.

The EL205(TA)-V optoisolator is a reliable and efficient device for controlling relays and transmitting signals between two circuits. Its efficient I/V conversion ratio, high voltage insulation, and wide application field make it an ideal choice for a variety of applications.
