Relay main product technical parameters

① Rated working voltage: refers to the voltage required by the coil when the relay is working normally. It can be AC voltage or DC voltage depending on the type of relay.
② DC resistance: refers to the DC resistance of the coil in the relay, which can be measured by a multimeter.
③ Suction current: refers to the minimum current that the relay can produce the suction action. In normal use, the given current must be slightly greater than the draw current for the relay to work steadily. The working voltage added to the coil, generally do not exceed 1.5 times of the rated working voltage, otherwise it will produce a large current and burn the coil.
(4) Release current: it refers to the maximum current generated by the release action of the relay. When the current in the draw state of the relay decreases to a certain degree, the relay will return to the unenergized release state, and the current at this time is far less than the draw current.
⑤ Contact switching voltage and current: refers to the voltage and current that the relay allows to load. It determines the size of the voltage and current that the relay can control. It can not exceed this value when used, otherwise it is easy to damage the contact of the relay.
