opto isolated ar atar modha difference ki

"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।

ভাইয়া দুইটা VCC/GND পিন কিভাবে ব্যবহার করব? আমি Single Channel এরটা আগে ব্যবহার করেছি, তাই বুঝতে পারছিনা।

দুইটি VCC এবং দুইটি GND পিনই তাদের নিজেদের মধ্যে সংযুক্ত (Short-Circuit) । তাই যে কোন একটি VCC/GND ব্যবহার করলেই হবে।
