Q: Can i control water pump or same high load device using this relay module? Questioned by Nadimulhuq, 03-May-2016

Q: can i control water pump or same high load device using this relay module? Questioned by Nadimulhuq, 03-May-2016

It does depend on the load. The "4 Channel 5V Relay Module" can perform with 10A 250V AC and 10A 30V DC. Answered by FAHIM_REAZA, 03-May-2016 11:46 AM

If you want to perform with high voltage, then please use opto-isolated relay module. The maximum load of our “1 Channel 12v 30A Opto Isolated Relay Module” is: AC 0V to 250V/30A and DC 0V to 30V/30A and ½ HP 240V AC. If our module fulfilled your requirement, then we will suggest you to use it. [Link: ] Answered by FAHIM_REAZA, 03-May-2016 12:03 PM

Q: can i use it with PIC microcontroller for On Off light fan in our home by android phone? (sorryim beginner) Questioned by Simonn, 10-Jun-2016

Yes, you can use. Answered by FAHIM_REAZA, 11-Jun-2016 07:51 AM

Q: Do we have 4 channel 12V relay module? If we don't please tell me can use it in place of the 12V module. Questioned by Khalid149, 18-Sep-2017

No. Sorry. We got 1 channel and 10 channel. Not 4. Answered by A.R, 19-Sep-2017 03:56 AM

Q: ভাইয়া দুইটা VCC/GND পিন কিভাবে ব্যবহার করব? আমি Single Channel এরটা আগে ব্যবহার করেছি, তাই বুঝতে পারছিনা। Questioned by abuobaidazishan, 25-Dec-2020

দুইটি VCC এবং দুইটি GND পিনই তাদের নিজেদের মধ্যে সংযুক্ত (Short-Circuit) । তাই যে কোন একটি VCC/GND ব্যবহার করলেই হবে। Answered by FAHIM_REAZA, 28-Dec-2020 07:26 AM

Q: opto isolated ar atar modha difference ki Questioned by KRZArpon, 15-Apr-2021

"4 Channel 5V Opto Isolated Relay Module" এ ইনপুট পিনকে Relay এর কয়েল থেকে Isolate করে রাখা হয়েছে। আর এ কারণেরই মডিউল দুইটির Control Signal এর মধ্যে পার্থক্য রয়েছে । অর্থাৎ "4 Channel 5V Relay Module" এর CHx পিনে Logical High (5V) দিলে নির্দিষ্ট Relay ON এবং Logical Low (0V) দিলে Relay OFF হবে। যেখানে "4 Channel 5V Opto Isolated Relay Module" এর জন্য Relay ON করতে Logical Low (0V) এবং Relay OFF করতে Logical High (5V) ব্যবহার করতে হবে। Answered by FAHIM_REAZA, 15-Apr-2021 10:03 AM
