1 Channel Relay Module 5V

The 5V Single Channel Relay Module is a compact and reliable switching module that allows low-voltage microcontrollers to safely control high-voltage and high-current loads. It is widely used with Arduino, AVR, PIC, ARM, DSP, 8051, and other TTL-compatible development boards for automation and embedded applications.

The module features a 5V electromechanical relay with a low-level trigger input, requiring less than 5mA of trigger current, making it easy to interface directly with microcontroller GPIO pins. An onboard transistor driver improves switching performance while the indicator LEDs provide clear power and relay status feedback.

With Normally Open (NO) and Normally Closed (NC) relay contacts, the module offers flexible control for AC and DC loads such as lights, fans, pumps, motors, and household appliances. Its isolation design helps reduce interference and improves overall system reliability.
