Description

2 Channel Relay Module Relay Board Arduino Relay Module.  With Optocoupler allows a wide range of microcontrollers. Such as Arduino, AVR, PIC, ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs. 4channel relay interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliance

Specifications Of 2 Channel Relay Module Relay :

  1. 5V 2-Channel Relay interface board, and also each one needs 15-20mA Driver Current
  2. Equiped Equipped with high-current relay, AC250V 10A ; DC30V 10A
  3. Standard interface that can be control 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

Meaning of High level and Low-level

High-level trigger refers to using the anode voltage at the VCC connection way of a trigger. And triggers the end when the trigger side has the positive voltage or to trigger voltage when the relay is off.

Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
