5V 1 Channel Relay Module-

This is a High and Low Level (user configurable) 5V 1 channel relay interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliances and equipment with a large current. It is equipped with high-current relays that work under AC250V 10A or DC30V 10A. It has a standard interface that can be controlled directly by the microcontroller. This module is optically isolated from the high voltage side for safety requirement and also prevent ground loop when interfacing with the microcontroller.

This 5V 1 Channel Relay Module is used for controlling electrical circuits or devices. It’s commonly employed in various projects and applications where you need to switch high-power or high-voltage loads using a low-power microcontroller or digital signal. This relay module has one channel, which means it can control a single electrical circuit or device.

This 5V 1 Channel Relay Module module supports both high-level and low-level trigger modes. You can configure it to trigger when the input signal goes either high (typically 5V) or low (typically 0V or ground). This flexibility allows it to work with various microcontrollers and digital signal sources. Relay modules like this are commonly used in home automation, robotics, IoT (Internet of Things) projects, and other applications where you need to control lights, fans, motors, or other electrical devices using a microcontroller or digital logic.

When using this relay module, you’ll need to provide a 5V power source to power the module itself and connect the input pins to your microcontroller or control system. By sending the appropriate trigger signal (high or low, depending on your configuration), you can control the state of the relay, which, in turn, opens or closes the electrical circuit connected to its output terminals.

Input Terminals

DC+: Connect the positive pole of the 5V power supply.
DC-: Connected the negative pole of the 5V power supply.
IN: Signal trigger input (3.3V to 5V, high or low-level signal selected via a jumper).

Output Terminals

NO: The normally open interface.
NC: The normally closed interface.
COM: The common interface for both normally open and normally closed.

How it Works

High-Level Trigger:

When IN is a LOW-level signal, the NO does not connect with COM and the NC connects with COM.
When IN is a HIGH-level signal, the NO connects with COM and the NC does not connect with COM.

Low-Level Trigger:

When IN is a LOW-level signal, the NO connects with COM and the NC does not connect with COM.
When IN is a HIGH-level signal, the NO does not connect with COM and the NC connects with COM.
