Frequently Asked Questions
Q: What is the purpose of a relay module? A: A relay module allows a low-voltage control signal, such as 3.3V from a microcontroller, to switch a separate higher-voltage circuit on or off, enabling control of devices like lights, pumps, or motors.
Q: How do I use these modules in a project? A: Each module provides input pins for the control signal, power, and ground, along with output terminals for the relay contacts. The optocoupler helps isolate the control side from the switched load side.
