Application Examples
What are the reliability of the relay?
1. The influence of the environment on the reliability of the relay: The relay working in GB and SF has the highest mean time between failures, reaching 820,000h, while in the NU environment, it is only 60000h.
2. The influence of quality level on the reliability of relays: When the relay of A1 quality level is selected, the average time between failures can reach 360,000h, while the average time between failures of the C level relay is 110,000, which is 33 times the difference, which shows the quality of the relay. The grade has a great influence on its reliability performance.
3. The influence of the contact form on the reliability of the relay: The contact form of the relay will also affect its reliability. The reliability of single-throw relays is higher than that of double-throw relays with the same number of poles. Increased reliability gradually decreases. The mean time between failures of single-pole single-throw relays is 5.5 times that of four-pole double-throw relays.
4. The influence of structure types on the reliability of relays: There are 24 types of relay structures, and different types have an impact on its reliability.
5. The influence of temperature on the reliability of the relay: The working temperature range of the relay is between -25～70℃. As the temperature increases, the relay's mean time between failures gradually decreases.
6. The influence of the action rate on the reliability of the relay: With the increase of the relay action rate, the mean time between failures basically shows an exponential downward trend. Therefore, if the designed circuit requires the relay to operate at a very high rate, then the relay needs to be carefully inspected to replace it in time when the circuit is repaired.
7. The influence of current ratio on the reliability of the relay: The so-called current ratio is the ratio of the working load current of the relay to the rated load current. The current ratio has a great influence on the reliability of the relay, especially when the current ratio is greater than 0.1, the mean time between failures drops rapidly, and when the current ratio is less than 0.1, the mean time between failures is basically the same, so the rated current should be selected in the circuit design Larger loads can reduce the current ratio, which can ensure that the relay and even the entire circuit do not reduce reliability due to fluctuations in operating current.

The Function Application
Signal on relay on, start delay, delay until relay off. After signal on 3 seconds,relay on and delay, delay 1 hour. If signal on 3 seconds then delay off, and relay off.
