Description
A 6 Channel 5V Relay Module is an electronic board that allows you to control up to six high-power devices (like lights, fans, or appliances) using low-power signals from microcontrollers like Arduino, Raspberry Pi, or ESP32.
Key Features
-
Number of Relays: 6 independent relays.
-
Control Voltage: 5V (ideal for most microcontrollers).
-
Relay Output: Typically rated at 10A 250V AC or 10A 30V DC.
-
Triggering: Each relay can be triggered individually via IN1–IN6 pins.
-
Optocouplers: Many modules use optocouplers for isolation between low-voltage control side and high-voltage relay side.
Pinout
-
VCC: Connect to 5V power supply.
-
GND: Ground.
-
IN1 to IN6: Control pins for each of the 6 relays. Apply LOW (or HIGH, depending on module type) to activate.
-
JD-VCC (if present): Power supply for the relay coils (can be separated from the logic circuit for protection).
