1 Channel 5V Relay Module without Optocoupler

The 1 Channel 5V Relay Module without Optocoupler is a single-channel relay board that runs on 5V DC and switches up to 10A at 250VAC and 10A at 30VDC, featuring an onboard LED that lights when the relay is active and a PCB with screw mounting holes for panel or enclosure fixing. This 5v relay module does not include an optocoupler isolation component, making it a simpler and more affordable circuit than isolated relay modules.

The control signal circuit and relay coil share a common ground, which is suitable for hobby projects, low-voltage DC switching, and prototyping where galvanic isolation from the load is not a design requirement. The single channel relay module onboard status LED gives instant visual confirmation that the relay has switched without needing a multimeter or serial monitor — useful during testing and debugging of relay control code on Arduino.

The 1 channel 5v relay module’s screw mounting holes allow it to be fixed securely inside a project box or panel, rather than sitting loose on a breadboard. This one channel relay arduino module is ideal for beginner 5V relay switching and hobby projects. StemVolt offers fast and reliable delivery with trusted service support.
