5v Relay Module Single Channel (Without Optocoupler) - ADIY

ADIY 1 channel 5v relay module is designed for switching only a single high powered device from your Arduino. It has a relay rated up to 10A per channel at 250VAC or 30VDC. There are two LEDs on the relay module indicating the position of the relay. We have three channels of the relay broken out to screw pin terminals. The channels are labeled for their function: common (COM), normally closed (NC), and normally open (NO). On the other side of the module, there are three pins – a Ground pin and a VCC pin to power the module and an input pin IN to control the relay. The input pin is active low, meaning the relay will be activated when you pull the pin LOW and it will become inactive when you pull the pin HIGH.
