12V automotive relays operate up to the maximum voltage of a fully charged lead-acid battery, about 15V. The current capacity depends on the particular relay's contacts.Apr 26, 2013
Can I use a 12V relay in a 24V system?
Just doubtful. 24V relay never work at 12V weather is a AC or DC voltage. If you want to know the pickup voltage of relay, you just set testing setup with variable voltage source.
How do you wire a 24 volt relay?

Can you power a 24VDC relay with 24VAC?
No,because 24VDC is a rectified 24VAC and will be alternating whiles the the relay actually needs a direct voltage supply to function properly. Anything that operates on AC can not be powered by DC without getting damaged.
What is an SPDT relay?
The SPDT Relay(30A) is a high quality Single Pole Double Throw Relay(SPDT). The Relay consists of a coil, 1 common terminal, 1 normally closed terminal, and one normally open terminal. When the coil of the relay is at rest (not energized), the common terminal and the normally closed terminal have continuity.
Is 24V DC the same as 24V AC?
As there will be a bridge rectifier in the device that you are powering, if you used a 24V DC, instead of 24V AC supply, the voltage inside the unit will be down by 29% than normal, this is because rectified AC would produce nearly 34V DC inside the device being powered.
Can I use 24VAC for 12VDC?
If you've ever been on a job installing a 12VDC device with only a 24VAC power source, you need to buy a couple of these to keep on your truck. This compact device converts voltages from 20-28VAC to 12VDC(1.5A). Great for CCTV Cameras, Access Control, Fire Systems, and security applications.
Can you use DC on an AC relay?
Just as it is impractical to operate a DC relay from AC, it is likewise impractical to operate an AC relay from DC. However, in an emergency, an AC relay may be operated from DC—provided certain precautions are taken.
