This project is a 2 Channel Relay Board.

Description

2 channel Relay driver project can be controlled by feeding 2-12V trigger voltage, Very useful project for application like Micro-Controller based projects, Remote controller, Lamp on Off, and any circuits which required isolated high current and high voltage switching by applying any TTL or CMOS level voltage. Two LED works as operation indicator while in , 3 pins screw terminals to connect load and provides both normally open and normally closed switching.

Input: 12 VDC @ 84 mA
Output: Two SPDT relay
Relay specification: 5 A @ 230 VAC
Trigger level : 2 to 12 VDC
Header connector for connecting power and trigger voltage
LED on each channel indicates relay status
Power Battery Terminal (PBT) for easy relay output connection
Four mounting holes of 3.2 mm each
PCB dimensions 49 mm x 68 mm

Can be easily convert as a remote switch by an infra-red T / R link , then it is very useful.

C1 is a filtering cap, used to reject noise from the power source, any 0.1uF cap will do the job.

Dear

If i Want to use 5v Relay What Should I need to Change in the Circuit? In additional to it i also want to add HLK-PM01 – AC-DC-converter to supply 5v Relay More over I also want to connect this Relay to Arduino Uno or Node Mcu Via Wifi.

Awaiting for reply
