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
