Optoisolators are electronic components that provide optical isolation of two circuits from each other. They enable electromechanical and electronic equipment to send and receive signals with greater efficiency. This article focuses on the S2S3Y application field and working principle of Optoisolators - Triac, SCR Output.
A Triac is a three-electrode alternating current (AC) switch in which current-controlled current and voltage-controlled current are both produced. It is a versatile device that can be used for switching, temperature control, and dimming. When combined with an optical isolator, the Triac can provide optical isolation of two circuits from each other, even when they are operating at different voltages. This makes the Triac suitable for use in applications where the need for electrical isolation is paramount.
An SCR, or silicon controlled rectifier, is a four-layer diode that is triggered when a current is applied to the Gate terminal. It is a four layer device with two P-type and two N-type channels. When connected to an AC voltage, the SCR will act as a switch, turning on and off the circuit as the voltage changes. When connected to the output of an Optoisolator-Triac, the SCR can be used to control AC devices.
Optoisolators are often used to protect circuits from external voltage surges, and also to maintain electrical isolation between two signals. For these reasons, the use of Optoisolators in different applications has become increasingly popular. The S2S3Y type of Optoisolator is specifically designed for Triac and SCR Output applications. This type of Optoisolator has an LED (light emitting diode) for the transmitter circuit and a photo-transistor for the receiver circuit.
The working principle of S2S3Y is quite simple. The LED in the transmitter section lights up when a voltage is applied to the Triac. This light is then detected by the photo-transistor in the receiver section, and a corresponding voltage is applied to the SCR. This process creates a controlled current in the SCR circuit, which can then be used to control an AC device.
Optoisolators are a reliable and efficient way to maintain electrical isolation between two circuits. The S2S3Y type of Optoisolator is especially well-suited for Triac and SCR Output applications, as it can provide optical isolation even when the two circuits are operating at different voltages. This type of Optoisolator can also be used to protect circuits from external voltage surges, as well as to control AC devices.
