5V Relay module 1 Channel (without optocoupler)

5V Relay Module 1 Channel 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.

Description

ADIY 1-channel 5V control Single-Pole Double-Throw (SPDT) High-level trigger AC power relay board can be controlled directly via a microcontroller and switch up to 10A at 250 VAC. The inputs of 1 Channel 5V Relay Module are isolated to protect any delicate control circuitry.The default state of the relay when the power is off for COM (Power) to be connected to NC (Normally Closed). This is the equivalent of setting the relay board IN pin to HIGH (has +5V sent to it). A wide range of microcontrollers such as Arduino, AVR, PIC, ARM, etc can be used to control this 5V relay module
