What is the difference between 24v relay and 220V relay

(Summary description)24v relay, current 10A. The power is 2200W. When the empty object is less than 2200W, you can choose a 24V relay, regardless of the voltage, look at their current, and multiply the current by 220V to get the power. Anything less than this power can be used.

24v relay, current 10A. The power is 2200W. When the empty object is less than 2200W, you can choose a 24V relay, regardless of the voltage, look at their current, and multiply the current by 220V to get the power. Anything less than this power can be used.

24v relay manufacturers

Similarly, 220V 24v relay is generally a small relay, mainly used for electronic or other low-power low-voltage circuits. The 220v intermediate relay is generally used as an intermediate conversion between high-power or high-voltage and hand-controlled operating devices to achieve the personal safety of the operator or to meet the requirements of the high-power load on the current and voltage of the control circuit.

According to the voltage, if the 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, use 24v relay, then the relay coil will be burned out. In addition to the coil The power supply voltage is different, is there any difference in other usage aspects, for example, in terms of driving the load, it depends on the size of your load, and the relay used is determined according to the size of the load. The load used cannot exceed the rated load of the relay, and it is best to leave a certain margin.

What are the main considerations when choosing? You can choose two, but how big your motor is, the maximum load of these two relays is 5A, and your motor load cannot exceed 5A. In addition, the motor has a relatively large starting current when starting, which is about normal 4~7 times the operating current, so there must be a margin. Another, when the motor is turned off, there is a large reverse voltage, which may reach hundreds of volts or more. At this time, the arc will ablate the relay. Contacts.

It is recommended to choose a 24v relay similar to these two models. They have reverse diodes (also called freewheeling diodes) and RC inside, which can restrain the reverse voltage impact and protect the relay contacts. However, the turn-off time is correspondingly extended, but they are all ms-level, and will not affect the voltage applied to the coil when the voltage is 380V. The motor has no speed at the moment of power-on, and all power consumption is consumed in the coil, so the current is started. That is 20 times the normal operation. When the motor reaches the rated speed, the actual current is also the rated current, so from 20 times the starting current to 1 times the current, according to the value of time, the average starting current per unit time is 4-7 times.
