The EL8171IS-T13 optocoupler is commonly used in the following applications:

1. Signal isolation in industrial control systems
2. Voltage level shifting in digital logic circuits
3. Isolation of sensitive components from high-voltage signals
4. Power supply feedback control in switch-mode power supplies
5. Motor control and drive circuits
