Hi,
I have used four 12VDC relays (each has diode on them) where I am using 12VDC with 1Amp current from a transformer. Problem is after 30 minutes of working, transformer and all relays becomes too hot that its hard to hold my finger on them. why its so ? Please guide me as i want them under normal temperature throughout days till they run.
Even I used 9Volts with 1 Amp , but still they become hot. and when I use 12V with 500ma even then scenerio is same.... is there any resistance i need ? or any other thing???
Please help me out...
