Long life relay
Web3 de mai. de 2015 · 5 Answers. Relays tend to be quite reliable in benign environments, however they have a limited lifetime. Typically something like 50,000-100,000 operations … WebContact Life The electrical life expectancy of general purpose and power relays is generally rated to be 100,000 operations minimum, while mechanical life expectancy may be one million, 10, or even 100 million operations. The reason electrical life is rated so low compared with mechanical life is because contact life is application dependent.
