How to use it for more efficient use of power relays

Relay This is a relatively common industrial appliance, but for the use of relays, many consumers still have some questions, such as how to use the power relay to better use, electromagnetic high-power relay is an automatic control circuit A commonly used component. In fact it is an automatic switch that controls a large current with a small current. Therefore, it is widely used in electronic devices. Electromagnetic high-power relays generally consist of a coil, iron core, and several sets of reeds with contacts.

Below on the electromagnetic high-power relay characteristics of the parameters, types of symbols and application principles, the following we follow the relay editor to learn more about the characteristics of parameters: electromagnetic high-power relay main characteristics of the parameters are as follows:

1. Rated operating voltage or rated operating current: This refers to the voltage or current required by the coil when the high-power relay is operating. The configuration of one type of high power relay is generally the same. In order to adapt to different voltage circuit applications, a type of high-power relay usually has a variety of rated operating voltage or rated operating current, and the difference between the specifications and models.

2. DC resistance: This refers to the DC resistance of the coil. Some product specifications give rated operating voltage and DC resistance. At this time, the rated operating current can be obtained according to Ohm's law. If the rated operating current and DC resistance are known, the rated operating voltage can also be determined.

3. Suction current: It refers to the minimum current that the high-power relay can generate a pull-in action. In practical use, to make the high-power relay reliably pull in, the given voltage can be equal to or slightly higher than the rated working voltage. Generally do not exceed 1.5 times the rated operating voltage. Otherwise it will burn the coil.

4. Release current: It refers to the maximum current generated by the high-power relay to release the action. If the current of the high-power relay that is in the pull-in state is reduced, when the current is reduced to a certain degree, the high-power relay returns to the state when it is not energized, and this process is called release of the high-power relay. The release current is much smaller than the pull-in current.
