According to the designing requirement of relay protection, the paper analyses the bad handling ability of single a / d converters, the conflict between high speed and high precision of vfc, low precision in inside a / d of mc9s12dg256, then brings forward the ad7890 which include multi - path switches, track / hold and a / d circuits. in addition, the traditional digital output circuit consists of parallel interfaces. photo - electricity segregation and middle relays, which are complex and low reliable
傳統的開關量輸出電路結構一般由并行介面、光電隔離和中間繼電器組成,光禍多,電路復雜,可靠性差,我們採用mc33291作為開出介面晶元,大大提高了保護動作的可靠性,提高了驅動能力, mc33291的sp工介面也簡化了開出電路,減少了pcb板面積。
