This module contains two relays that are electrically isolated from the controlling input. The relays can be used to switch higher voltage and current loads than a microcontroller can traditionally accomplish.

Features

  • Powered from 5V
  • 2 channels
  • Can be used as Normally Open (NO) or Normally Closed (NC)
  • Optically isolated inputs

Specifications Of 2 Channel Relay Module Relay :

  1. 5V 2-Channel Relay interface board, and each one needs 15-20mA Driver Current
  2. Equiped Equipped with high-current relay, AC250V 10A ; DC30V 10A
  3. Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic active low)
  4. Opto-isolated inputs
  5. Indication LED’s for Relay output status

Module interface Of 2 Channel Relay Module Relay:

  • The positive (according to the relay voltage VCC: connect power supply)
  • GND: connect power negative
  • IN1: relay module (effective) high-level trigger signal trigger end
  • IN2: relay module (effective) high-level trigger signal trigger end
