I have this problem on relay that it didnt have an output voltage when we energize the coil.I check the continuity of the normally open contacts(it become close now when i apply voltage to the relay coil.I check the pin configuration with the broken relay-its the same.

what is the reason behind why is it that i dont have the voltage output? Is there any way that i can modify the said relay?

thanks

 

A relay is a switch that gets turn ON or OFF electrically instead of mechanically by hand.

A relay will not output any voltage by itself. However, it will allow a voltage/current from one side of the open contact to pass over to the other side when you powers up the relay coil.

 

The coil side of a relay and the LOAD side are not connected electrically.

This allows you to use mixed types for switching.
For instance, You can use 5vDC to energize a coil that allows 120vAC through the LOAD side.
