Optoisolators can be used to electrically isolates two circuits, while transmitting a control signal from one circuit to another. This is accomplished by fiber optic coupling of the two circuits. One common type of optoisolators is the Triac, SCR Output optoisolator. One example is the IL4118-X017T optoisolator made by Isocom Components. This optoisolator has an isolation voltage of 5.2 KV RMS.The IL4118-X017T optoisolator is composed of an LED emitter and a Triac (solid-state switch) receiver in one 8 pin DIP (dual in-line plastic) package. The LED is a gallium arsenide infrared emitter which is optically coupled to a Triac. It is capable of continuous load currents of 30mA at 800V. The packages have a current transfer ratio of 0.4% minimum and a high isolation voltage of 5.2 KV RMS.The working principle of the IL4118-X017T optoisolator is fairly straightforward. The LED emitters emits an infrared light, which is picked up by the Triac receiver on the other end. The Triac then conducts when a voltage is applied across it, allowing current to pass through the device. When the voltage is removed, the Triac stops conducting and the circuit is isolated again.The IL4118-X017T optoisolator is a useful device for applications such as switching and controlling AC power in home and industrial automation systems. It is also used in a variety of control and instrumentation applications, such as level detectors, position detectors and timing circuits. It allows for the control of AC power without any electrical contact between the control circuit and the controlled circuit, ensuring high electrical safety due to its high isolation voltage.In addition, the IL4118-X017T optoisolator has very low propagation delay, providing reliable operation and precise timing control. The device is also highly reliable with a minimum MTBF of 500,000 hours. It has an operating temperature range of -55 to +150°C and is UL approved.The IL4118-X017T optoisolator is a versatile device with numerous applications in a variety of fields. It provides isolation between two circuits, allowing for reliable and precise control of AC power in applications such as home and industrial automation systems. It has excellent reliability and a high isolation voltage and is useful for a variety of control and instrumentation applications.
