The 12V relay coil is controlled by a 12V controller but the 12V relay's contact is connected a 24V power source (so will it cause any issues?).

it just says a 12V relay. It hasn't specified rated voltage for the relay contacts. The relay part number is B120-7022

Who is the manufacturer? Never mind.
Part is obsolete and no datasheet is available from Eaton. So I guess you're SOL.

Mostly a relay coil voltage and contact voltage are quite separate. The only exception I am aware of is older automotive horn relays that only have three terminals. So a relay intended for 12 volt application will work quite well switching 24 volt power. Coil and contact ratings are quite separate.
