| Abstract: | In this paper, aimed at the problem that the number of channels of general digital I/O card can not satisfy the requirement of large-scale digital I/O in the control system, a scheme of extending digital I/O channels is presented. Then a kind of 32-channel photoelectrically isolated multiple digital I/O card is designed. Finally through a simple example, a method of extending multiple I/O channels is demonstrated, and its effectiveness is proved. |
