Are there any differences, drawbacks or advantages of driving big loads with a 5V energized relay and 24V energized relay? I've seen a manufacturer which has 2 similar cards. One is driving smaller contactors and the other is driving bigger contactors. It uses 5V relays for smaller ones and 24V relays for bigger ones. I wondered if this has a reason? Do you have any idea? Thanks.
 

5V Relay 24V Relay

Driving loads with relay with any rated voltage, may be 5 or 12 or 24, doesnt matter untill the Load capacity of the relay is higher than the load connected to it. After all the load and the coil are isolated and the coil is fed with a different volatge.
 

Re: 5V Relay 24V Relay

Different types of relay rating are used for driving different loads because as the load current increases the thickness of d coil that can support it ought to increase else the coil will burn/cut. As the voltage rating of relay increases the coil thickness also increases.

Are there any magnetic related matter?

Sorry i didnt get your words "Are there any magnetic related matter?" I think "Absolutely No". The coil side is not at all related to load bieng switched. The coil side will have a different volatge whereas you may use a load with any other voltage on the other side...Cheers
