Main product technical parameters of relay

Update:30-04-2021
①Rated working voltage: refers to the voltage required by the coil when the relay is working normally. Depending on the type of relay, it can be AC ​​voltage or DC voltage.
② DC resistance: refers to the DC resistance of the coil in the relay, which can be measured with a multimeter.
③Pick-in current: refers to the minimum current that the relay can produce a pull-in action. In normal use, the given current must be slightly larger than the pull-in current, so that the relay can work stably. As for the working voltage applied to the coil, generally do not exceed 1.5 times the rated working voltage, otherwise it will produce a larger current and burn the coil.
④Release current: refers to the maximum current that the relay generates to release the action. When the current in the pull-in state of the relay is reduced to a certain level, the relay will return to the unpowered release state, and the current at this time is much smaller than the pull-in current.
⑤ Contact switching voltage and current: refers to the voltage and current allowed to be loaded by the relay. It determines the magnitude of the voltage and current that the relay can control, and this value cannot be exceeded during use, otherwise it is easy to damage the contacts of the relay.
