The 5V Single Channel Relay Module 10A is a normally open switch that controls a relay capable of switching much higher voltages and currents than your standard Arduino boards. When the control pin is driven low, a green LED is lit. When the relay is activated, an audible click is heard. A logic HIGH deactivates the relay, and the LED goes off. Specifications: Model: KY-019 Maximum load: AC 250V/10A, DC 30V/10A Trigger current: 5mA Working voltage: 5V Module size: 43 x 17.8 x 16.5mm (L x W x H) Note: The Relay Brand can change. Module Connections 1 x 3 Header GND = Connect to the ground of the 5V power supply IN1 = Relay control input 1. Logic LOW level energises relay 1 Vcc = Connect to 5V power supply Relay Contacts NC = Normally Closed side of the relay Centre Terminal = Common terminal usually connects to the load power source NO = Normally Open side of the relay Package Includes: 5V Single Channel Relay Module 10A Check out our Clearance and on-sale items.
