  • Working at 3V or 5V to control relays.
  • Each relay can switch a variety of AC or DC high voltage
  • High current loads working at 110V or 220V AC mains like lights, fans, motors and such.
  • The status of the relay is indicated by the RED Led.
  • One normally closed contact and one normally open contact

1 CH 5V active low Relay Board

The 5V relay module is suitable for SCM development, and home appliance control. It is with a 5V~12V TIL control signal which can control DC / AC signal. The module is perfect for common applications. It has an 5V-12V TTL control signal that can control DC/AC signal. This 5V relay can control 220V AC load which is useful to control a motor, a led strip, or any other module. 

The relay can control any device just like a switch contact. Its contact is isolated from the driven circuit. This relay features an LED Indication of Relay ON. Direct input from 3-5V Microcontroller for relay control. The output terminal for relay contacts. Provision of 2x3Pin male header for wire connection. Powered from external 5V or from the male header. The relay has a contact rating of 5A at 240V AC

Note: It is important that the microcontroller share ground with the relay board along with other control signals else it will not able to control the relay.

Also check the 1CH 5v Optocoupler Relay Board available on the Robocraze website. The relay board is designed to control higher current loads like solenoids, motors, lights, and fans.

1. What is 5V 1 channel relay?

The 1 Channel 5V Relay Module provides a single relay that can be controlled by any 5V digital output from your microcontroller. The relay is accessible using screw terminals and can handle up to 2A of current. A handy LED indicates the status of the relay.

2. What is a single-channel relay module?

The Single Channel Relay Module is a convenient board that can be used to control high voltage, and a high current load such as motor, solenoid valves, lamps, and AC load. It is designed to interface with microcontrollers such as Arduino, PIC and etc.

3. How do relay boards work?

Relay boards are computer boards with an array of relays and switches. They are designed to control the voltage supply and have input and output terminals. Relay boards provide independently programmable, real-time control of multiple onboard relay channels.

4. What is the use of 1 channel 5V relay module?

A 1 channel 5V relay module is a powerful and versatile tool for controlling high-voltage or large current electronic devices using low voltage microcontrollers. With its compact size and efficient design, this relay module serves as a reliable interface between the control system and the controlled device in various industrial automation applications. It can easily switch AC or DC loads up to 10A with input signals from sensors, buttons, relays, or switches. This makes it an essential component for home automation systems, security systems, robotics projects and more. Its simple installation process combined with its affordable price point make it suitable for both professional engineers and DIY enthusiasts alike.

5. What is the working principle of 5V relay?

A 5V relay is an essential component in various electronic devices, from household appliances to industrial machinery. Its working principle involves a low voltage coil that creates a magnetic field when activated by an external signal or control unit. This magnetic field then attracts the armature and closes the circuit of higher voltages, allowing current to flow through and power up the device. The use of relays eliminates the need for directly connecting high-voltage circuits with delicate control units, providing safety and versatility in multiple applications. With its reliable operation and compact design, it has become a preferred choice for designers seeking efficient solutions without compromising on performance.
