EL852 is an optoisolator that isolates input and output circuits. It is available in either a transistor or photovoltaic output. This type of optoisolator is typically used to protect sensitive electronic equipment from electrical transients and to provide a way of isolating the electrical circuit from hazardous voltages.The EL852 consists of an infrared light-emitting diode (LED) and a phototransistor. The LED is placed inside a black plastic housing. When the LED is illuminated by an external electrical signal, it emits light that can be detected by the phototransistor. The phototransistor then switches on and off in response to light from the LED.EL852 optoisolator in a transistor output consists of a phototransistor and a bias resistor. The phototransistor is used to detect the light from the LED and to switch the output transistor on or off. When the LED is illuminated by an electrical signal, it emits light that is detected by the phototransistor. The phototransistor then switches the output transistor on or off depending on the state of the LED.In a photovoltaic output, the EL852 optoisolator consists of a photovoltaic cell, a current limiting resistor and an output diode. The photovoltaic cell is used to sense the light emitted by the LED and to generate a voltage signal that is proportional to the intensity of the light. The current limiting resistor sets the amount of electrical current that can flow through the output diode. The output diode then switches on or off depending on the voltage generated by the photovoltaic cell.The EL852 optoisolator can be used in a variety of applications. It can be used to switch or regulate electrical signals in consumer products such as televisions, stereos and household appliances. It can also be used in industrial applications such as motor speed regulators and process control systems. It is also used in automated teller machines to provide electrical isolation between the user and the machine.The EL852 optoisolator is an effective and reliable device that provides excellent electrical isolation between two circuits. It is available in both transistor and photovoltaic output types and can be used in a variety of applications. It provides electrical isolation between the input and output circuits and can protect sensitive electronic equipment from electrical transients.
