From your jpg image itself you can easily make out the voltage is 12VDC. The current you can find as I explained in the earlier post. Please refer the details carefully.
Please let me know what kind of relay you are using. Normally the operating voltage of the relay (ie the voltage to be applied to the coil) must be mentioned in the relay itself. Please checkout anything like DC12V/ DC24V in your relay..
