Question:

The power supply voltage of the relay is not the same as the control voltage

The power supply voltage of the relay is not the same as the control voltage

Answer:

The voltage of the relay is the voltage required by the relay action, which is the voltage applied to the relay coil, which is generally low and easy to control the circuit design; and the control voltage is the allowable voltage of the relay contact, which can be high, such as 5V DC operation of the relay can control 220V AC, where 5V is the relay power supply voltage, 220V is the control voltage.

Of course not the same, you said the power supply voltage is added to the coil voltage, generally 5V, 12V, 24V and several other, plus the power supply voltage relay to pull, after the contact contact on the contact,

You can control the other electrical power, and this is what you call the control voltage, this is the relay specified by the contact voltage, generally can control 220V AC, or 380V three-phase power, depends on the relay marked voltage value.
