4 Way 5V Relay Module

4 Channel 5V Relay Control Board

The 4-channel relay control board is a relay module that operates with a 5V supply voltage and is compatible with Arduino and many other microcontroller platforms. It enables safe control of loads that require high voltage and current using low-voltage control signals.

Each relay channel draws approximately 20mA of current during triggering from the microcontroller. The relays are triggered with a logic 0 (0V) signal. The board includes status LEDs for each relay channel, allowing easy visual monitoring of the active state.

The onboard relays can switch loads up to 10A at 30V DC or 220V AC. NC (Normally Closed), NO (Normally Open), and COM terminals are brought out for each relay. This provides flexible usage for different switching scenarios.
