Dear Guys,
Cool Morning to all!
I am interfacing My Micro board by max232 to My system.. Micro board consists of 4 relay . Each relay is driving up to 12V 2A current.. Resistive load.. Relays are Isolated by Opto-cuopler (MCT6)... Without load total system is working fine. while connecting load System gets hanging problem.. mean ma application window not responding some times...
For more info:
Relays are Isolated.
Load Tracks is totally separated from Micro controller Unit....
What is the reason for this problem...? Expecting your valuable feedback
Is there any Opto-coupling based Rs-232 interfacing(IC) available in market?
