Optoisolators are special type of electrical components that enable signals to travel between two electrical systems without the systems actually being electrically connected. The IL4118-X007T is a Triac, SCR Output optoisolator, which provides isolation between control and load circuits while transferring signals from one to the other. The IL4118-X007T isolator can be used to switch AC loads of up to 400V/8.3A.

Application Field and Working Principle

The IL4118-X007T optoisolator has a wide range of uses, from motor control and lighting control to industrial automation and commercial applications. It can be used in a variety of scenarios where the need for electrical isolation or signal transmission is required. The IL4118-X007T can be used to switch AC loads of up to 400V/8.3A and is suitable for applications such as motor speed control, lamp control, and others.

The working principle of the IL4118-X007T is based on the principle of transformers. An optical signal is passed through an LED, which is detected by a photodiode. The voltage induced in the photodiode due to the electrical current generated by the LED excitation is then transmitted to the output, where the voltage is rectified, filtered and inverted to drive a triac. The triac is then used to switch the connected AC load.

The IL4118-X007T is designed to be an extremely reliable and robust component, with a maximum operating temperature of 100°C, and a high level of insulation to ensure safe operation. It also features a wide operating range of 5 - 24V, and a low-voltage control current of 0.3mA, allowing for accurate switching without the need for additional circuits.

The IL4118-X007T optoisolator is designed to be a low-power, low-cost component that can guarantee reliable operation and long lifespan. It is a great choice for applications that require signal isolation and the safe switching of AC loads.
