| Abstract: | This paper introduced the notion of safety grade in EN954-1. The all faults self-test technology of the jeteye entire self-test active opto-electronie protective device that included the real-time self-test of electric circuit faults, the security of sensing signal in transmission and identification, and the end output signal examined technique was discussed. The new technology that the jeteye entire self-test active optoelectronic protective device had and the safety grade that it achieved were explained by comparisons of some domestic and international peers. |
