Optoisolators have been used for decades in a variety of electrical systems to provide electrically isolated connections between components. Specifically, the EL817(S)(B)(TU)-V optoisolator belongs to a device family known as transistor, photovoltaic outputs. It is used to electrically isolate a low current input signal from a high power circuit. The EL817(S)(B)(TU)-V optoisolator is a high isolation type optoisolator well suited for motor control, contact sensor interface, and many other applications where protective isolation is required.

The working principle of EL817(S)(B)(TU)-V optoisolator is based on light emitting diode (LED) with phototransistor as the switching element. As current flows through the LED, it emits light which is detected by the phototransistor. This phototransistor, in turn, switches on, allowing current from the input section to flow through the output section. The input current and the input voltage are separated by an insulation barrier, allowing for a high degree of noise suppression and isolation.

The EL817(S)(B)(TU)-V optoisolator is a highly applied device with many potential uses, including motor control, industrial temperature control, contact sensor interface, digital optical communication systems, and many other applications. In motor control, it is typically used as a means of supply a motor with a pulse-width modulated (PWM) signal. In industrial temperature control, it is used to isolate and adjust the temperature of a control loop. In contact sensor interface, it is used to detect when a contact has been made or broken, such as in a push-button switch.

For digital optical communication, the EL817(S)(B)(TU)-V optoisolator is generally used to transmit digital signals over optical cables. In these applications, the device can be used to build a safe communications link between different electrical systems. This is made possible by the fact that the output current and voltage of the device are completely isolated from the input signal.

One of the most unique applications of the EL817(S)(B)(TU)-V optoisolator is in data transmission systems. In these systems, the optoisolator is used to transmit digital signals over optical cables, while also providing isolation between different systems. This is done by modulating the LED current to match the data being sent. The modulated LED current is then detected by the optoisolator’s phototransistor, allowing the data signal to be relayed to the desired location.

The key advantage of EL817(S)(B)(TU)-V optoisolator is its high level of isolation. This advantage makes it ideal for a variety of applications, from motor control to industrial temperature control and contact sensor interface. Additionally, its ability to transmit digital signals over optical cables makes it an ideal solution for many applications, including digital optical communication systems. Its broad range of applications, combined with its high level of isolation, make the EL817(S)(B)(TU)-V optoisolator a versatile and useful device for many different applications.
