Temperature is one of the key factors affecting the performance of the relay. In a high temperature environment, the internal material of the relay may expand, resulting in increased contact resistance, which in turn affects the performance of the relay. In addition, high temperature will accelerate the aging of the plastic and insulating materials inside the relay, the contacts may be oxidized and corroded, arc extinguishing is difficult, the technical parameters of the electrical components decay, and the reliability is reduced. On the contrary, in a low temperature environment, the material of the relay will shrink and the contact resistance will decrease, which may also cause the relay to operate unstably. Therefore, in order to ensure the stable operation of the relay, you should pay attention to the influence of the ambient temperature when using it, and choose a relay model suitable for the environmental conditions.
The power supply voltage is an important factor affecting the operation of the relay. If the power supply voltage is unstable or does not match the rated voltage of the relay, it may cause the relay to operate unstably or fail to operate. In order to ensure the stable operation of the relay, you should ensure that the power supply voltage is stable and select a power supply that matches the rated voltage of the relay.
Load is also an important factor affecting the performance of the relay. This power relay needs to withstand a current of 16A or 20A, so the size and type of load will have a direct impact on its performance. If the load is too large, the contacts of the relay may burn out prematurely, causing the relay to fail. At the same time, the load type will also affect the power carrying capacity and service life of the relay. Therefore, when selecting a relay, you should choose the appropriate relay model according to the load size and type, and pay attention to its rated load.
Under low pressure conditions, the heat dissipation conditions of the relay will deteriorate, and the coil temperature will increase, which may cause changes in the given pull-in and release parameters of the relay, affecting its normal operation. In addition, sand and dust pollution may also cause wear or blockage on the contacts of the relay, thereby affecting its performance. Therefore, when using relays in an environment with severe sand and dust pollution, appropriate protective measures should be taken.
Electromagnetic interference may interfere with the normal operation of the relay. In an environment with strong electromagnetic interference, the relay may be affected by the interference signal and cause misoperation or refusal to operate. Therefore, when selecting a relay, its anti-interference ability should be considered, and appropriate shielding measures should be taken to reduce the impact of electromagnetic interference.
