Siginar sadarwa na PHD-11TC-11 shine shigarwa cikin keɓantaccen shingen tsaro, wanda zai iya gane hanyar sadarwa ta hanyoyi biyu na RS-485 Half Duplex siginar dijital a cikin wuri mai haɗari da wuri mai aminci. Da'irar tana ba da rarraba wutar lantarki don kayan aikin kan shafin. Ana iya canza ƙimar ƙarfin lantarki ta hanyar maɓallin bugun kira na sama. Ana nuna takamaiman hanyar aiki a cikin ginshiƙi da ke ƙasa.
Wannan samfurin yana buƙatar samar da wutar lantarki mai zaman kanta, kuma ana keɓe wutar lantarki, shigarwa da fitarwa.
