  • ULN2003 IC used to drive Relays (better than Transistor Drive Circuits)

4 Channel 12V ULN2003 based Relay Board

Relay board module is used for controlling higher current loads from your microcontroller development board, PC parallel port or Arduino Uno. This board has four (4) on-board relay which can switch up to 7Amps. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy.

The relay is safely driven by ULN2003 IC hence your input device, such as Arduino, is protected from the relay circuit and IC will further protect your microcontroller from relay kickback. This is a 12V 4-Channel Relay interface board which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, 8051 and so on.

It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc- High-quality screw terminals (Terminal Block) provided (C, NC, NO) for quick and easy connection- Input Signal Pin connected to Burg stick for easy accessibility- LED Status indicators to indicate the relay ON/OFF status.- Mounting holes provided

1. How to connect a 4 relay module to Arduino?

  • It's very easy to connect the 4 relay modules to the Arduino  and  you can control many devices through the Arduino including  AC and DC. In this example, we will connect a simple load like an LED to the output of the relay and drive it with the Arduino. First, connect the Arduino's 5V to the 4-relay module's VCC, and the Arduino's ground  to the 4-relay module's ground. Next, we need to connect the communication pins IN1, IN2, IN3 and IN4 to the Arduino data pins 7, 6, 5 and 4. A 3V battery is used to light the LED. So I connected the positive side of the battery to the positive side of the LED, the negative side to the COM of each relay, and the NO to the negative side of the LED.

2. What are the applications of 8  channel relay module?

  • The 8-channel relay is isolated, safe, reliable, and anti-interference.  8 channel relay is widely used for all MCU control, industrial field, PLC control and smart home control. It can be directly connected to and  controlled  by microcontrollers such as Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic.

Works Perfectly - Thanks!

This is the first website which provides electronic components that actually cares about its customers even after purchase. Saying this becasue I have experienced the following: * Delivers at the right time, sometimes when they don't deliver on time they make sure to inform beforehand. * Received the right products in perfect condition
