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.
