Description

Product Description:

The relay module is useful for various IoT (Internet of Things) projects, allowing you to automate your projects. It can control devices that operate at 230V AC or 30V DC and consume up to 10A.

Technical Specifications:

Maximum load: AC 250V/10A, DC 30V/10A
Trigger current: 5mA
Control voltage: 5V DC
Dimensions: 50 x 26 x 18.5mm
4 mounting holes on the PCB with a diameter of 3.1mm

Connection Example:

To create this connection example, you will need the following:

1x DC 5V power supply capable of providing a minimum current of 1A
1x 2-channel relay module controlled by 5V
1x UNO development board || Reference TXVMOK_DB-UNO-R3 *for the version with the development board
     Various wires needed to make electrical connections (optional buttons)

Connection example without development board:

By pressing the buttons connected to GND (or directly contacting the wires) in the above schematic, you will be able to control the 2 relays.

Connection example with development board:

If you want to control the relays from a microcontroller or development board, you will need to remove the jumper between RY-VCC and VCC and power the relays separately through the VCC and GND pins, as shown in the following image:

Code example:

const int Relay1 = 7;
const int Relay2 = 6;
void setup() {
pinMode(Relay1, OUTPUT);
pinMode(Relay2, OUTPUT);
}
void loop() {
digitalWrite(Relay1, HIGH);
digitalWrite(Relay2, LOW);
delay(1000);
digitalWrite(Relay2, HIGH);
digitalWrite(Relay1, LOW);
delay(1000);
}

In the example with the Uno development board, the state of the relays will alternate every 1 second.
