Relay Module (5V-10A) 2Channel (Low level trigger)

You can not control switching on/off your home lamp or laundry directly with arduino or microcontroller. To do that you need relay module.

This relay module consists of 2 relays. Each relay is connected to a current  buffer so that you can connect them directly to a Microcontroller or Arduino.

Using these relays you can easily control high power devices or appliances using arduino or microcontrollers, the relay is rated for 230V 10Amps. The Module has 5 LED’s, one for power and 2 for indicating relay signals.

Specifications

Rating:  10A  (250V AC or 30 V DC)

Input voltage: 5V DC

How to connect

The connections to your Arduino (or microcontroller) side:

• VCC – supply voltage. 5V from my Arduino.
• IN1 – set to HIGH (1) to set the relay to its “default” state(Relay not Work)
  set to LOW to switch the relay to its alternate state (Relay Work)
• IN2 – same as IN1, but controls the second relay on the board
• GND – ground
