The influence of temperature and humidity:
The temperature affects the operating performance of the relay. In general, the higher the temperature, the higher the operating voltage of the relay. Therefore, in order to ensure the smooth operation of the relay, please use the recommended temperature. If the ambient temperature exceeds the temperature specified in the product specifications, you need to evaluate the relay to determine whether it can use or not. Humidity will affect the contact performance of the relay. In general, the greater the humidity, the relay contact surface is more likely to produce oxide film, which may leads to the failed phenomenon of poor contact.
Refer to the product specifications when using it. Usually humidity> 90%, the general selection is sealed relays.
