Click here to be notified by email when Relay Module for Arduino (4 Channels - 5V) becomes available.


This relay module consists of 4 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 4 for indicating relay signals.

Specifications

Rating:  10A  (250V AC or 30 V DC)

Input (Control) 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 to set the relay to its "default" state, set to LOW to switch the relay to its alternate state
  • IN2 - same as IN1, but controls the second relay on the board
  • IN3 - same as IN1, but controls the second relay on the board
  • IN4 - same as IN1, but controls the second relay on the board
  • GND - ground

 

The connections to your power Device side:

  • NC: Normally close
  • COM: Common
  • NO: Normally open
