Design and Construction
The module features a compact PCB with an onboard relay, control circuit, LED indicators, header pins, and screw terminals. The 3-pin screw terminal provides easy access to the relay’s COM, NO, and NC contacts for connecting the load.
The onboard LEDs provide visual indication of the module’s power and relay operating status. Header pins for power and control signals make it convenient to connect the relay module to development boards using suitable jumper wires.
Its compact 48 × 29 × 17 mm form factor allows it to be easily integrated into electronics projects and control panels.
Working Principle
The relay is controlled through the IN control pin. When the module receives the appropriate low-level trigger signal, the relay coil is energized and the relay changes its contact state.
In the activated state, the COM and NO contacts are connected, allowing a normally disconnected load circuit to be switched ON. When the relay is inactive, COM and NC remain connected, allowing normally closed operation.
This enables a low-voltage microcontroller signal to control a separate electrical load through the relay’s isolated switching contacts.
Relay Output
- NO (Normally Open): The contact remains open when the relay is inactive and closes with COM when the relay is activated.
- COM (Common): Common relay contact used for connecting the load circuit.
- NC (Normally Closed): The contact remains connected to COM when the relay is inactive and opens when the relay is activated.

Product Disclaimer
The relay’s specified contact rating should be considered when selecting a load. Motors, pumps, transformers, and other inductive loads may require additional protection against switching transients.
High-voltage AC connections can be hazardous. Use appropriate insulation, wiring, fusing, and electrical safety practices when connecting mains-powered appliances.
Arduino, Raspberry Pi, jumper wires, power supplies, appliances, motors, and other accessories are not included unless specifically mentioned in the package contents.

FAQs – 12V 1 Channel 10A Low Level Trigger Relay Module
1. What is the 12V 1 Channel Relay Module used for?
It is used to control AC or DC electrical loads such as lights, fans, pumps, motors, and appliances using a low-voltage control signal.
2. How many devices can it control?
It has 1 relay channel, so it can control one load or switching circuit at a time.
3. What is the relay operating voltage?
The relay operates at 12V DC.
4. What type of trigger does the module use?
It uses a low-level trigger, meaning the relay activates when the control input receives the required LOW signal.
5. What is the maximum switching capacity?
The relay is rated up to 250V AC at 10A or 30V DC at 10A.
6. What are NO, COM, and NC?
- NO: Normally Open contact
- COM: Common contact
- NC: Normally Closed contact
7. Can this module be used with Arduino?
Yes. It can be used with Arduino and other compatible microcontroller systems, provided the control and power requirements are properly matched.
8. Can it be used with Raspberry Pi?
Yes. It can be used with Raspberry Pi through an appropriate control interface and power arrangement.
