The EL814M-V optoisolator is a transistor-photovoltaic output device that offers the benefits of optical isolation. The device features a single-channel, open-collector NPN output, making it suitable for a range of applications.Optoisolators are used to provide electrical isolation between two circuits. This isolation is achieved through the use of an optically coupled pair of devices, usually an LED and a phototransistor. The optoisolator allows the electrical signal from one circuit to be optically transmitted and received by the other circuit without the two circuits coming into direct electrical contact with each other. As such, Optoisolators provide a high level of electrical noise and surge protection, making them an attractive option for use in a variety of applications.The EL814M-V optoisolator consists of an LED enclosed in an epoxy package and an NPN phototransistor connected in a plastic package. The LED and the phototransistor are optically coupled, meaning that the light emitted by the LED is received by the phototransistor, thus converting an electrical signal into an optical signal. This signal is then transmitted to the open-collector output of the device, which is capable of sinking up to 50mA.The device is suitable for use in a range of applications, including push-pull switching, logic gate switching, level shifting, as well as analog and digital signal buffering. The EL814M-V can be used to sense the presence of external conditions such as temperature, pressure, humidity, or current, as well as to sense the change in amplitude of an applied signal such as voltage or frequency.The device operates at a forward LED current of 10mA, with a peak forward voltage of 2V. The optoisolator also features an isolation voltage rating of 50Vrms, and a reverse voltage rating of 5V. The device is also resistant to high voltage transients, with a pulse withstand rating of 50V.In terms of operation, the EL814M-V optoisolator works by converting an electrical signal into an optical signal through the use of an LED and an NPN phototransistor. The optical signal is then transmitted to the open-collector output of the device, which is capable of sinking up to 50mA. The use of the optoisolator eliminates the possibility of electrical interference between two circuits, thus providing a high level of noise and surge protection.The EL814M-V optoisolator is a versatile and reliable device, making it an attractive option for a range of applications. Its ability to isolate signals optically ensures high levels of noise and surge protection, while its compatibility with a wide range of external conditions makes it suitable for a variety of applications. As such, the EL814M-V optoisolator is an ideal solution for providing electrical isolation and signal switching in a variety of applications.
