Optoisolators, or optical couplers, are a type of electrical component used to electrically isolate sections of a circuit from each other. These components combine both optical and electrical technologies to achieve high-level electrical isolation, up to 4000 Volts often in the range of 2500 – 5000 Volts. The EL816 (A) is an optoisolator of type transistor, photovoltaic output, with an operating voltage between 5 to 190 Volts and a switching frequency of up to 5kHz.

The EL816 (A) uses a photodetector and an LED placed across a gap, to electrically isolate two circuits from each other. The gap between the two devices is crucial here, since it ensures that the two parts of the circuit are not able to directly interact. When a voltage is applied to the LED, it emits light which passes across the gap and is absorbed by the photodetector. This creates a photocurrent in the photodetector which is then used to activate the output transistor. The transistor acts as a switch, allowing current to flow from one side of the circuit to the other.

The EL816 (A) is a great way to add an extra layer of safety to circuits and systems, since it electrically isolates the two parts of the circuit and eliminates the risk of potential grounds between them. It can be used to safely control large current or voltage flows, and in cases where high levels of electrical isolation are needed, such as when dealing with medical equipment or working with hazardous materials.

The EL816 (A) is an excellent way to add electrical isolation to a circuit, while still keeping things as simple as possible. The optical isolation technology used in the device eliminates the need for complex and expensive circuits, while still providing reliable electrical isolation. It is especially useful in applications where high-level isolation is needed, and is one of the most reliable optoisolators in its class. The EL816 (A) is an excellent choice for applications needing high isolation and reliability, while still maintaining a low cost.
