Hello Everyone,

I am using 24V relay with avr microcontroller. Everything works fine except the relay. The ULN2003 shows correct voltages when switching is done. The circuit works only where there is a pullup resistor on the output, the switching between 0-24 is also correct. Only issue is when I connect a relay it doesn't work. I have checked the relay, it is just fine. When the relay is connected to ULN2003, it doesn't work.

Why is it happening.

attach the circuit diagram.
 

Are the relays connected like
