Optoisolators are devices that use a light-emitting diode (LED) to transmit electrical signals across an airspace or insulator, while preventing contact between two circuits. Such devices may be used to increase safety and accuracy in measurements and protect both circuits from potentially hazardous electrical conditions while improving the speed and stability of signal transfer. The EL816(S)(X)(TA) Transistor Photovoltaic Output Optoisolator to which this article applies is among the many integrated boards available, and this will cover its application field and working principle.

The EL816(S)(X)(TA) Optoisolator is designed for a wide variety of high-speed switching applications including switching power supplies, relay drivers, and motor controllers. El816(S)(X)(TA) provides isolation between that two circuits of up to 3750Vrms and is used to reduce the possibility of any voltage spikes affecting the circuitry connected to it. It is a high-performance optoisolator with phototransistor output. It provides excellent linearity, low input current requirements, and high isolation voltage performance.

This Optoisolator is specifically designed for power supply applications that use a low-voltage isolated output and a main power supply voltage that is greater than or equal to 120VAC or 160VDC and through to 240VAC input. The operating temperature range for the EL816(S)(X)(TA) Optoisolator is -40°C to +125°C and maximum power dissipation is equal to 300mW. It also has a high isolation of 3750Vrms and a forward current of 10mA.

In terms of the EL816(S)(X)(TA) Optoisolator’s working principle, this type of device passes electrical signals between the two connected circuits using light signals. A light-emitting diode (LED) is used to drive a current into the phototransistor, which in turn switches the output. Current flow in the LED\'s anode and cathode results in a light signal sent across the airspace or insulating barrier between the two isolated circuits, which will then be received by the phototransistor on the other side.

The EL816(S)(X)(TA) Transistor Photovoltaic Output Optoisolator is thus a highly reliable, advanced optoisolator with a power supply insulation of up to 3750Vrms and an operating temperature range from -40°C to +125°C. Used mainly in switching applications for power supplies, motor controllers, and relay drivers, the EL816(S)(X)(TA) Optoisolator delivers reliable performance, as well as excellent linearity and low input current requirements.
