1, Rated working voltage: refers to the normal work of the relay coil voltage. Depending on the type of relay, is the AC voltage, but also the DC voltage.
2, DC resistance: Refers to the coil in the relay DC resistance, measured by a multimeter.
3, Pull-in current: refers to the relay generates a smaller pull-in current. In normal use, the given current slightly larger than the pull-in current, the relay can work stably. The
coil plus the operating voltage, not more than 1.5 times the rated
operating voltage, otherwise it will have a larger current and the coil
burned.
4, The release of current: refers to the relay to generate a larger release current. When the relay pull-in current is reduced to, the relay will be restored to the power release. The current is much smaller than the pull-in current.
5, Contact switching voltage and current: refers to the relay allows the load voltage and current. It
determines the relay can control the size of the voltage and current,
when used can not exceed this value, otherwise it will damage the relay
contacts.
