Solid State Relay SSR with 2 Channels 12V 2 Triggers and Stable Fuse for 240V 2A

Description

What it is

The solid state relay SSR with 2 channels 12V is an electronic device that allows controlling the flow of current in an electrical circuit through a digital signal. In practice, it acts as an electrically controlled switch, activated by a low-voltage (12V) electrical signal.

Features

• 2 independent channels
• Supply voltage: 12V
• Switching voltage: 240V
• Switching current: 2A
• Includes a stable fuse for circuit protection
• Reverse current protection

What it is for

The 2-channel 12V SSR relay is ideal for controlling high-voltage electrical devices from a microcontroller like Arduino or ESP. It can be used to create automatic lighting systems, motor control, solenoids, and other devices that require high switching power.

Tutorial: How to use 2-channel Solid State Relay SSR

The solid state relay SSR with 2 channels 12V is an essential component for anyone who wants to control electrical devices from a microcontroller like Arduino. Ideal for beginners and intermediates, it allows managing loads up to 2A at 240V.

What you need

• Arduino uno or compatible
• connection wire
• 12V power supply

Steps

1. Connect the 12V power supply to the relay
2. Connect the relay trigger pins to the Arduino output pins
3. Write the Arduino sketch to control the relay
4. Check that the devices connected to the relay turn on and off as expected

Example code

const int triggerPin1 = 2;
const int triggerPin2 = 3;
void setup() {
  pinMode(triggerPin1, OUTPUT);
  pinMode(triggerPin2, OUTPUT);
}
void loop() {
  digitalWrite(triggerPin1, HIGH);
  delay(1000);
  digitalWrite(triggerPin1, LOW);
  delay(1000);
}

Mini project

Create an automatic lighting system that turns lights on and off based on a timer or a light sensor

Common mistakes

• Connect the relay to a voltage higher than specified
• Do not verify the polarity of the power supply
• Do not add protections such as pull-down resistors
• Use an excessive load

Recommended accessories

• Light sensors
• Connected relays
• Protective fuses
• Pull-down resistors
