POTTER & BRUMFIELD T9AV1D12-22 22VDC RELAY
Also try Hosfelt, Marlin Jones, Allelectronics, Allied, Jameco.
You can use any relay with a 24v coil but the coil impedance/current needs to be as low or lower than this relay. 1w @ 22v = 45 mA. If the coil runs on DC the coil resistance is ~490 ohms.
The 30A contact rating probably needs to be for a motor load.
