1. Rated voltage, this is the voltage required for the relay to work normally. Different models have different voltages. Some are DC and some are AC.
2. DC resistance refers to the DC resistance in the relay, and a multimeter can be used to test the resistance value.
3. The release current refers to the maximum current released by the relay during operation. In the case of pull-in, after the current becomes smaller, the relay will return to the state of no power supply, so that the current will be less than the pull-in current.

4. The release current refers to the maximum current released by the relay during operation. In the case of pull-in, after the current becomes smaller, the relay will return to the state of no power supply, so that the current will be less than the pull-in current.
5. Electric shock switching current and voltage is the current and voltage that the relay can load. It can control the size of the current and voltage. When using it, it cannot exceed the released current value, otherwise it is easy to damage the relay.
