Question about my first relay module

Hi everyone

I'd appreciate some help regarding my understanding of how a relay module works. Here is the story:

I recently got this relay: http://grobotronics.com/relay-module-1-channel.html

in order to connect it to my arduino and be able to power an LED strip from IKEA.

The LED strip is DC12V (and 0.6W)

Now, my question is this:

On the relay, the DC indications are as follows:

10A 30VDC 10A 28VDC

Does this actually mean that when the relay is on, it will supply the LED strip with 30 (or 28) Volts? If so, I suppose the LEDs will be fried (since they operate with 12V), is this correct?

Or the indications on the module are actually limits, meaning that it will power up devices requiring up to 30 (or 28) Volts?

I feel quite embarrassed to ask such a silly question, but from what i have found online so far, I have not been able to find an answer.

Thanks in advance!

Cheers John

The relay does not supply anything.

The relay does not power anything.

You had better read what a relay is. http://www.explainthatstuff.com/howrelayswork.html

Those are contact ratings as per certification agency approval. http://microcontrollershop.com/product_info.php?products_id=5919

OMG, please disregard this thread, I just realized how wrongly I had understood the concept of the relay. The relay actually serves as a switch, not providing any voltage...

Thanks anyway! John

Those numbers you quoted are the MAXIMUM ratings. You can switch 12V with you 30V relay just fine.
