Yes, the voltage you described should be fine.

You should buy relays with 12V DC coil because that’s the steady state output voltage from OpenSprinkler DC (e.g. it’s roughly equal to the input voltage). Technically, OpenSprinkler DC outputs an impulse 24V DC when the station/zone is activated, but then it drops that voltage to the input voltage in steady state.
