1, rated working voltage
Refers to the relay work required voltage coil. According to relay models, can be AC voltage, also can be DC voltage.
2, DC resistance
Refers to the DC resistance in the relay coil, through the universal meter.
3, rated current
Is the relay can produce attracting action of the minimum current. In normal use, given current must be slightly greater than the rated current, so the relay to work steadily. To coil the working voltage, generally do not exceed the rated voltage 1.5 times, otherwise it will produce a larger current and the coil burning.
4, release current
Refers to the maximum current relay product release action. When the pull-in state of the relay current decreases to a certain extent, the relay will be restored to a powered-off release status. When the current is far less than the rated current.
5, contact switching voltage and current
Is a relay allows loading voltage and current. It determines the relay to control the size of voltage and current, use can not exceed this value, otherwise it is easy to be damaged and the contacts of the relay.
