These 1 Channel 24V Relay Modules offer a 30AMP switching current at up to 240V AC or up to 30V DC, but are controlled with a common 24V DC coil voltage. This means that you can integrate almost any other Hobbyist Electronics into your 24V powered project without hassle, and you could even choose to mix in some AC voltages as well so that you can also switch basic home appliances and other AC goods without being too concerned about that AC escaping into your DC circuit.
