This 5V one-channel relay module provides a controller-friendly way to switch a separate load from an Arduino-compatible board or another compatible control circuit. Its relay offers COM, normally open (NO) and normally closed (NC) contacts, so the required default load state can be selected at the screw terminals.
Connections and relay contacts
- VCC: 5V module supply
- GND: common ground for the control side
- IN: control-signal input
- COM: common relay contact
- NO: normally open relay contact
- NC: normally closed relay contact
Key specifications
- Control voltage: 5V DC
- Listed trigger type: high-level input
- Minimum listed drive current: 4mA
- On-board working-status LED
- Listed contact capacity: up to 10A at 250VAC or 10A at 30VDC
- Approximate module size: 41 × 16 × 16mm
- Approximate weight: 12g
Applications
Suitable for learning projects, lamps, small automation prototypes and other loads that remain within the verified contact rating. The controller provides the logic signal; the relay performs the isolated mechanical switching action. Check the module markings and supplied jumper arrangement before power-up because board versions can differ.
Safety guidance
Mains voltage can cause serious injury or fire. Use suitable insulation, an enclosure, clearances and over-current protection, and have high-voltage wiring completed or checked by a suitably qualified person.

Frequently Asked Questions
What control voltage does this one-channel relay module use?
The listed module uses a 5V DC control supply and provides one relay channel.
What do COM, NO and NC mean on the relay terminals?
COM is the common contact, NO is normally open and NC is normally closed. Choose NO or NC according to the required default load state.
Can this relay module switch mains voltage?
Its listed relay contact rating includes AC loads, but mains wiring is hazardous. Installation must use proper insulation, enclosure, clearances and a suitably qualified person.
Does this relay module have a status indicator?
Yes. The listed module includes an on-board LED that indicates its working status.
Can this module be used in an automation project?
Yes, when the control signal, 5V supply and connected load remain within the module's verified ratings. Use proper protection and qualified wiring practices for hazardous voltages.
