Overview

This is a single channel 5 V, low level trigger relay module, which allows you to control high voltage devices using a 5 V signal. This relay module is capable to work with voltages up to 220 VAC, making it ideal for home automation.

Specifications

  • 1 channel 5 V low level trigger relay module
  • High-current relay
  • Safe and reliable
  • Easy installation
  • Can control AC or DC signals
  • Can control AC 220 V load
  • Can be used as home appliance control switch
  • Size: 45 x 16 x 20 mm

Note: The nominal voltage for the coil of the relay is 5 V.

Instructions for use:

1. Connect the load the to relay.

Load should be connected to the screw terminals.

Each relay has the following configuration:
Normally Open - Common - Normally Closed

The "Normally Closed" terminal is connected to the "Common" terminal when no voltage is applied to the control pin and the "Normally Open" terminal is disconnected. When voltage is applied to the control pin, "Normally Closed" is disconnected, connecting the "Common" and "Normally Open" terminals.

CAREFUL!!! Connect the load when it is not powered by the mains voltage to avoid accidents.

CAREFUL!!! Check that the load wires are not short-circuit after securing them to the screw terminals.

2. Write the code to control the relay.

Activating / deactivating the relay is very easy because all you have to do is to apply a voltage of 5 V on the "IN". If you are using an Arduino compatible development board, you need to follow the steps below to use the module:

In the "void setup ()" function you have to declare the digital pins that you use as output. Example: "pinMode (digitalPin, OUTPUT);" , where "digitalPin" is the digital pin you use to control the relay. 
BONUS: If you run out of available digital pins, you can also use the analog pins as digital.

In the "void loop ()" function you must use the following instruction to activate the "digitalWrite (digitalPin, HIGH) ;" and to disable it "digitalWrite (digitalPin, LOW);"
When you have finished writing the code, press the compile button to check for syntax errors.

3. Power on the module.

Connect the VCC and GND pins in the center of the module to the 5V and GND pins of the development board used.

4. Connect the digital pin to the control pin on the module.

5. Upload the code.

The final step is to upload the code.
