6 Channel Relay Module with light coupling 5V

The 6 Channel Relay Module with light coupling has six 5 V relays on one board, each with an optocoupler (light coupling) on its input to isolate your microcontroller from the relay side. It lets an Arduino, ESP32 or Raspberry Pi switch six separate loads such as lamps, fans, pumps, solenoid valves and door locks, which makes it a practical choice for home automation and control panels.

6 Channel Relay Module Specifications

• Channels: 6 independent relays
• Relay coil voltage: 5 V DC
• Input isolation: optocoupler on each channel
• Control inputs: IN1 to IN6, plus VCC and GND
• Outputs: COM, NO (normally open) and NC (normally closed) screw terminals on each relay
• Indicators: status LED for each channel

6 Channel Relay Module Applications

• Home automation: switching lights, fans and appliances
• Smart irrigation with pumps and solenoid valves
• Electric door locks and access control
• Wi-Fi controlled switch panels with ESP32 or ESP8266
• School, workshop and industrial control projects

What's in the Box

• 1 × 6 channel 5 V relay module

Tip: Check the contact rating printed on the relays before connecting a load, and take great care with 220 V mains: switch off the power, insulate all terminals and keep the board in an enclosure. On many versions the inputs are active low, so a relay turns on when its input pin is pulled to GND.
