Relay Module  (MR009-001.1) Rele for Arduino + galvanic insulation (galvanicky oddeleny)

This Relay Module is a module designed to allow you to control a single relay in a very simple and intuitive manner. Being compatible with Arduino, the most immediate way to use it is to connect it to an Arduino board using flexible jumpers.

Exploiting the characteristics of the relay mounted on the module and through the use of an Arduino digital I/O pin, it is possible to control motors, inductive loads and other devices; this product is therefore fundamental in domotics projects or, more in general, in robotics projects.

The module is equipped with an optocoupler on the IN line in such a way that it ensures the galvanic insulation between the relay load and the control board which drives this module.
