2 Channel 5V Relay Module With Optocoupler

Description

A relay is an electromagnetic switch used to control a high power device using a low power microcontroller boards (5V Microcontrollers). The onboard optocoupler isolates the peripheral and microcontroller to protect the main board from any reverse current. It can be used to control indoor devices like TV, Lights, Fans and more. Note that, you need to consider the power consumption of the appliance before using it. This relay module can handle up to 10A 250V AC at the output terminals and only 5V at the input.
