1-Channel 5V Relay Module

A single-channel relay expansion module with a 5V supply and low-level trigger input. It is suitable for microcontroller projects that need to switch an external load using a digital control signal.

Common applications

  • Arduino relay control
  • ESP32 automation projects
  • Lights, fans and small appliances
  • DIY control panels

Use appropriate electrical isolation and wiring practices when switching higher voltages.

Product Description:

  1. Features an isolation slot between the control area and the load area.
  2. Equipped with power indicator and relay status indicator: LED ON when activated (energized), LED OFF when deactivated.
  3. When a signal is present at the input pin, the common contact (COM) connects to the normally open (NO) contact.
  4. Can be used as a module for microcontroller development boards or for home appliance control.
  5. Capable of controlling DC or AC signals; can switch 220V AC loads.
  6. Includes one Normally Open (NO) and one Normally Closed (NC) contact.
  7. Blue KF301 terminal blocks make connecting control wires easier.

Explanation of High-Level and Low-Level Trigger Modes (For those who are unclear):

  • High-Level Trigger refers to a trigger mode where there is a voltage between the signal input pin and ground. This can be understood as triggering by shorting the signal input pin to the VCC positive terminal.
  • Low-Level Trigger refers to a trigger mode where the voltage between the signal input pin and ground is 0V. This can be understood as triggering by shorting the signal input pin to the GND negative terminal.
