No matter how many volts the relay 24v is, look at their current and multiply the current by 220V to get the power. Anything less than this power can be used.

The relay 24v, current 10A. The power is 2200W. When the empty object is less than 2200W, you can choose the relay 24v. Similarly, the 220V relay 24v is generally a small relay, which is mainly used for electronics or other low-power and low-voltage circuits. The 220v intermediate relay is generally used as an intermediate conversion between high-power or high-voltage and manual operation devices, in order to achieve the personal safety of operators or meet the requirements of high-power loads on the current and voltage of the control circuit.

According to your voltage, if your power supply voltage is 24V, then use 24V relay, if the power supply is 220V, then use 220V relay, if your power supply is 220V, you use 24V relay, then the relay The coil will be burnt and ask if there is any difference in other uses except the coil supply voltage. For example, if there is a requirement for driving the load, it depends on the size of the relay 24v load, and the relay used is determined according to the size of the load.
