產品功能：
對閥室、站(zhan)(zhan)場的(de)(de)陰極(ji)保(bao)(bao)護管地電(dian)(dian)位(wei)(wei)(wei)進行(xing)測量并轉換為(wei)4--20mA標準工業信(xin)號或RS485MODBUS信(xin)號，便于各級站(zhan)(zhan)控系統(tong)對設置點的(de)(de)陰極(ji)保(bao)(bao)護電(dian)(dian)位(wei)(wei)(wei)進行(xing)采集(ji)、監控和處理。電(dian)(dian)位(wei)(wei)(wei)傳(chuan)送(song)器(qi)(qi)的(de)(de)電(dian)(dian)源(yuan)供電(dian)(dian)側安裝有(you)B級SPD，提供電(dian)(dian)位(wei)(wei)(wei)傳(chuan)送(song)器(qi)(qi)的(de)(de)供電(dian)(dian)雷電(dian)(dian)過(guo)電(dian)(dian)壓保(bao)(bao)護，在電(dian)(dian)壓測量側安裝有(you)信(xin)號SPD，提供電(dian)(dian)位(wei)(wei)(wei)傳(chuan)送(song)器(qi)(qi)和站(zhan)(zhan)控系統(tong)的(de)(de)雷電(dian)(dian)過(guo)電(dian)(dian)壓保(bao)(bao)護，保(bao)(bao)護電(dian)(dian)位(wei)(wei)(wei)傳(chuan)送(song)器(qi)(qi)和站(zhan)(zhan)控系統(tong)不被雷電(dian)(dian)過(guo)電(dian)(dian)壓擊(ji)穿絕緣而導(dao)致損壞。
