5V 2 Channel Relay Module

The 5V 2 Channel Relay Module is a reliable switching solution designed to control two independent electrical loads using low-voltage logic signals. Operating on a 5V power supply, this module allows microcontrollers to safely control high-voltage AC or high-current DC devices.

Each relay channel is equipped with opto-isolation and driver circuitry, providing electrical isolation between the control side and load side. This improves safety and protects sensitive microcontroller pins from voltage spikes. The module supports normally open (NO) and normally closed (NC) contacts, offering flexibility in circuit design.
