Notes on the use of relays

点击率: Release time: 2018-04-13 14:18:41

1. Rated 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 either AC voltage or DC voltage.

2. DC resistance: refers to the DC resistance of the coil in the relay, which can be measured by a multimeter.

3. Pull-in current: It refers to the minimum current that the relay can generate 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 a larger current will be generated and the coil will be burned.

4. Release current: refers to the maximum current that the relay generates when it releases. When the current in the relay pull-in state is reduced to a certain level, the relay will return to the release state without power. 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 by the relay. It determines the size of the voltage and current that the relay can control. Do not exceed this value during use, otherwise the contacts of the relay will be easily damaged. Use technology; it means that the coil in the relay will generate a very high reverse electromotive force under the condition of losing current, and it is easy to damage the electronic devices that control it. In the process of use, it is important to consider the introduction of absorption circuits in the design circuit.
