OMRON H3Y-4 Time Relay 0-10 seconds 12V DC 5A 250VAC resistive timer relay

Description

What it is

The OMRON H3Y-4 timer relay is an electronic component that allows the activation of an electrical circuit after a predefined time, variable from 0 to 10 seconds.

Features

• Delay time: 0-10 seconds
• Supply voltage: 12V DC
• Switching current: 5A
• Switching voltage: 250VAC resistive

What it is for

The OMRON H3Y-4 timer relay is ideal for home or industrial automation projects where a timed control is necessary. It can be used to create timed lighting systems, alarm systems, or any other application that requires timed control of an electrical circuit.

Tutorial: How to use OMRON H3Y-4 Relay

The OMRON H3Y-4 relay is a resistive timer that allows controlling electrical circuits with an activation time of 0 to 10 seconds. Ideal for home or industrial automation projects where timed control is necessary.

What you need

• Arduino Uno or compatible
• connection wire
• 12V DC power supply
• connectors

Steps

1. Connect the relay to the 12V DC power supply
2. Connect the Arduino to the relay following the product documentation
3. Write the Arduino sketch to activate the relay
4. Upload the sketch to the Arduino
5. Test the relay operation

Example code

void setup() {
  pinMode(2, OUTPUT);
}

void loop() {
  digitalWrite(2, HIGH);
  delay(5000);
  digitalWrite(2, LOW);
  delay(5000);
}

Mini project

Create a timed lighting system for your garden or room. Connect the relay to a lamp and use the Arduino to automatically turn the light on and off.

Common mistakes

• Do not verify the correct power supply of the relay
• Do not configure the control pins correctly
• Do not test the functionality before integrating it into a larger project
• Use an activation time greater than 10 seconds

Recommended accessories

• Arduino Uno
• 12V DC Power Supply
• Connection Cables
• Protective Relay
