Overview

Wiring Connections

Power:

- VCC: Connect to a 5V power source. This powers the relay coil.
- GND: Connect to the ground of your power source.

Control:

- IN: Connect to a digital output pin of your microcontroller (like Arduino) to control the relay.

Relay Contacts:

- COM (Common): This is the common connection of the relay. Connect it to one terminal of the device you want to control.
- NO (Normally Open): Connect this to the other terminal of the device. When the relay is activated, it will connect COM to NO.

Power

Input Voltage:
- VCC: Requires a 5V DC power supply.
Current Consumption:
- Relay Coil: Typically around 70-100mA when activated.
- Relay Contacts: Can handle up to 10A of current at 250V AC.

Input and Output

Input:

- Control Signal: Requires a 5V DC logic signal to activate the relay.

Output:

- Relay Contacts: Can switch AC or DC loads up to the relay’s rated current (typically 10A).

Physical Characteristics

Dimensions: Approximately 50mm x 30mm.
Mounting: Includes mounting holes for easy installation on a surface or within an enclosure.
PCB Material: Typically FR-4 or similar.

Technical Specifications

Relay Switching Voltage: 250V AC / 30V DC (maximum rating).
Relay Switching Current: 10A (AC) / 15A (DC) at rated voltage.
Control Signal Voltage: 5V DC logic level.

Additional Features

Optocoupler Isolation: Protects the control circuit from high voltage spikes.
Status LED: Helps in visual verification of the relay status (on/off).
Reverse Polarity Protection: Some modules include protection against incorrect power connections.

How to Use

Power the Module:

- Connect the VCC pin to a 5V power supply.
- Connect the GND pin to the ground of your power supply.

Connect Control Signal:

- Connect the IN pin to a digital output pin on your microcontroller (such as Arduino). This pin will control whether the relay is on or off.

Wire Your Device:

- Connect one terminal of your device to the COM pin.
- Connect the other terminal of your device to the NO pin.

Control the Relay:

- To turn on the relay, set the digital output pin to HIGH (5V). The relay will close the connection between COM and NO, turning on the device connected.
- To turn off the relay, set the digital output pin to LOW (0V). The relay will open the connection between COM and NO, turning off the device.

Verify Operation:

- Observe the onboard LED to confirm the relay’s status. When the relay is activated, the LED will typically light up.

The 1-Channel 5V Relay Board Module is ideal for controlling high voltage devices with low voltage signals, making it a valuable component for various automation and control applications. Its ease of use and robust features make it a popular choice for hobbyists and engineers alike.
