Optoisolators are devices that allow a signal through from one interface to another, isolated electrically, by using light. The EL3H7(F)(TA)-VG optoisolator is a component of this type, composed of a phototransistor output, as the name implies, it is usually used as an isolator, when transmitting digital information. This device is used in systems that require high current and voltage electrical isolation between two circuits. The EL3H7(F)(TA)-VG optoisolator consists of an LED mounted on a printed circuit board, optically isolated from the output phototransistor. When a signal is received by the LED, it is converted to a photoelectric current, which activates the phototransistor, amplifying the input signal and delivering it to the output circuit.
Applications
The EL3H7(F)(TA)-VG optoisolator is used in a variety of applications which require high isolation between input and output signals. It is the perfect choice for applications in which electrical noise interference may be a problem, as the device keeps the input and output circuits electrically isolated, eliminating the possibility of electrical noise interference. It is also extensively used in SCADA systems, communication systems, industrial control systems, and process control systems.Working Principle
The EL3H7(F)(TA)-VG optoisolator works on the principle of photoelectric conversion. When a signal is received, it is converted to a stream of photons by the LED, which is then directed to the phototransistor, activating it and sending the signal to the output circuit. The phototransistor is usually connected to a source of constant current, making the phototransistor to gain the input signal and amplify it before sending it to the output.The EL3H7(F)(TA)-VG optoisolator provides high voltage and current insulation between the input and output circuits, allowing the transfer of signal without any electrical interference. This device is also suitable for use in extreme conditions, such as high temperatures, high vibration, and high moisture.Advantages of the EL3H7(F)(TA)-VG
The EL3H7(F)(TA)-VG optoisolator offers a variety of benefits, including a high degree of isolation, compact size, low power consumption, and immunity to electrical noise. This device is also very reliable and durable, with long-term operation even in extreme conditions. Furthermore, this device is also very easy to install and use, which makes it ideal for a variety of industrial and commercial applications.In conclusion, the EL3H7(F)(TA)-VG optoisolator is a device that is ideal for applications which require electrical isolation as well as high voltage and current insulation. It is a highly reliable and durable device, which is also easy to install and use. As a result, it is the perfect choice for systems that require a high degree of electrical isolation.The specific data is subject to PDF, and the above content is for reference
