Optoisolators are widely used to isolate input signals from the output driver, providing electrical insulation that prevents noise and electrical interference between circuits. The EL3081S(TB)-V, a type of optoisolators — triac, SCR output — is used between the output and the load driver to provide reliable isolation. This article examines the application fields and working principles of the EL3081S(TB)-V.The EL3081S(TB)-V is primarily used in static relay and solid state drive applications due to its exceptional isolation properties. It is also used for controlling motor drives, switching relays, regulating heater power, controlling thyristors, and monitoring currents in machine tools. This optoisolator also boasts a wide range of operating conditions it can work in, including temperatures ranging from -40°C to +85°C, and supply voltage ranging from 12V to 24V.The EL3081S(TB)-V optoisolator consists of a transistor output, a coupler, and a current limiting resistor. The transistor output is connected to the load driver and actively controls its operation, while the coupler contains an LED that emits light when the circuit is activated. When the LED is active, it emits light that is detected by the photocoupler, which in turn activates the transistor. This allows the EL3081S(TB)-V to switch on and off the load driver, providing an isolated control of the output signal.The optoisolator’s working principle is relatively simple and can be explained in a few steps. When the input voltage is applied, it is conducted over the LED in the coupler which causes it to light up. This light is then received by the phototransistor. The phototransistor then builds up a voltage level sufficient to turn on the transistor, thus allowing the current to flow through the output terminal to the load driver. In this way, the EL3081S(TB)-V optoisolator is able to isolate the input signal while still providing a controlled output.The EL3081S(TB)-V optoisolator is a reliable component that is capable of operating in extreme conditions while still providing sufficient isolation to the load driver. The device’s operating principles are simple and straightforward, meaning it is relatively easy to use and maintain. Its use in static relay and solid state drive applications makes it ideal for controlling various motor drives, switching relays, and other similar applications.To summarize, the EL3081S(TB)-V is an optoisolator — triac, SCR output — designed for use in static relay and solid state drive applications. It is capable of withstanding extreme operating conditions and provides isolation between the input and output signals. Its simple working principles make it easy to use and maintain, and it is able to control various motor drives, switching relays, and other applications.
