EL1018-G Application Field and Working Principle: Optoisolators - Transistor, Photovoltaic Output are devices that are used to provide electrical isolation between two circuits. The EL1018-G is a type of opto-isolator that provides this electrical isolation very reliably using a light-sensitive element. It is often used in high-voltage circuits such as those found in industrial or medical devices.The EL1018-G combines the features of both an optical transmitter and an optical receiver. The transmitter is a light emitting diode (LED), while the receiver is a photodiode or phototransistor. This combination provides a reliable electrical isolation between the two circuits, which can prevent interference between them.The EL1018-G is usually used to protect sensitive circuitry from being damaged by accidental high voltage surges. It blocks the current when the voltage goes beyond the rated voltage, thereby preventing any damage to the sensitive components. It also has the ability to suppress transient inductive spikes, protecting the circuitry from low-voltage surges.When the EL1018-G is used in DC circuits, it can be switched on and off quickly and reliably even when exposed to high voltage surges. This makes it ideal for applications that require reliable electrical isolation in DC circuits.In terms of working principle, the EL1018-G relies on the basic principle of light transmission. The LED emits light which is then absorbed by the photodiode or phototransistor. Depending on the mode of operation, the light received is either converted into an electric current or used to turn on and off the switch.When the light intensity is above the threshold, the switch will turn on and will remain in the on-state until the light intensity goes below the threshold. The EL1018-G can also be used as a current-limiting device as it will turn off before the rated load is reached. This ensures that the connected circuit will not be subjected to higher than the specified voltages.In summary, the EL1018-G is a type of optocoupler that can be used to provide effective electrical isolation between two circuits. It is reliable and can handle high electrical surge without damaging the connected circuitry. It can also be used as a current-limiting device to protect against overloading of the circuit.
