KY-019 5V 1 Channel Relay Module COM45,R18

DescriptionThe KY-019 is a 5V single-channel relay module designed to control high-voltage devices using low-voltage signals from microcontrollers like Arduino, Raspberry Pi, and ESP32. It’s commonly used in IoT projects to manage appliances such as lights and motors.Relay Capacity: Capable of handling up to 10A at 250V AC or 30V DC, making it suitable for controlling various high-power devices.Input Voltage: Operates with a 5V DC input, compatible with most microcontrollers. ​Control Signal Voltage: Recognizes a HIGH signal (3.3V to 5V) to activate the relay, allowing flexibility with different logic level controllers. ​LED Indicator: An onboard LED illuminates when the relay is active, providing a visual status indication. ​Pin Configuration:S (Signal): Connects to the control signal from the microcontroller.​ (VCC): Connects to the 5V power supply.​– (GND): Connects to the ground of the power supply.​Relay Output Terminals:NC (Normally Closed): Connected to the common terminal when the relay is inactive.​COM (Common): The common terminal for the relay switch.​NO (Normally Open): Connected to the common terminal when the relay is active.
