The 8-relay module is useful for controlling multiple high voltage devices using development pads such as Arduino.
This relay module can control high voltage devices, like the home appliances, using a 5V signal. Each relay is controlled by an optocoupler and needed 5 mA to control current.
It is capable to work with voltages up to 250 VAC and supports currents up to 10 A, making it ideal for home automation.
For example, you can remote control various home appliances remotely, via the internet or Bluetooth, using an Arduino development pad and the necessary shields.
