Información del producto

Single Channel Relay Module Characteristics:

  • Dimensions: 50 x 25 x 18.5 mm
  • Each 5V relay requires a current of 20mA.
  • Activation through a 5V signal that can be directly controlled by the microcontroller.
  • Tolerance: 250V AC / 30V DC 10A
  • CC+: Supply
  • Color: Color may vary

Module Interface:

  1. DC +: Positive supply (relay voltage according to the requirements)
  2. DC-: Negative supply
  3. IN: Relay control, can be high or low level

Relay Output:

  1. NO: Normally open relay interface - relay is open when not activated
  2. COM: Common Interface for Relays
  3. NC: Normally closed relay interface - relay is closed when not activated

High and Low End Trigger Selection:

  1. LOW: Shorting jumper for level-triggered low-end trigger
  2. HIGH: Shorted jumper for high-end trigger

Single Channel Relay Module Usage and Applications:

This module is designed to be controlled directly by a wide range of microcontrollers such as Arduino, PIC, ARM, and MSP430.

It can be used with Arduino Special Sensor Shield v.4.
Valid for microcontrollers like:

  • Arduino
  • 8051
  • AVR
  • PIC
  • DSP
  • ARM
  • MSP430
  • PLC
  • TTL logic

Usage in Arduino Projects:

The single-channel relay can be used with Arduino to control high-power or high-voltage devices such as lights, motors, appliances, etc. using low-voltage signals generated by Arduino.

Usage in Electronics:

In electronics, the single-channel relay is used to isolate low-voltage circuits from high-voltage circuits, allowing safe control of high-power devices with low-voltage devices.

Usage in Technology:

In technology, the single-channel relay can be integrated into automation systems to control the on and off switching of electrical equipment, such as automated lighting systems, automatic irrigation systems, among others.

Usage in Robotics:

In robotics, the single-channel relay can be used to control high-power motors, robotic arms, gripping systems, among other components that require currents and voltages higher than those that can be directly handled by microcontrollers.
