I use the electronic circuit control 24V relay, with 24V relay control high-power contactor, I would like to ask the general 24V relay coil power
there is a very simple way to calculate the relay power: first with a multimeter to measure the relay [coil resistance], and then divided by 24v [coil resistance], get the [relay operating current], then take 24v multiplied by [ Relay operating current], is the relay work when the actual power consumption.

Commonly used in general small 24V relay operating current between about 20 - 40mA, 24v x 0.04A (40mA) = 0.96 watts.
