概述
用于對用電線路中的三相電流進行實時測量與指示,并可通過擴展接口實現(xiàn)報警、變送、通訊功能。
技術(shù)參數(shù)
電流測量顯示范圍:AC 0 ~10A(直接測量)、 AC 0~999.9kA(外附電流互感器)
額定輸入電流:1A、5A
輸入頻率范圍:45~65Hz
測量準確度:0.5級
采樣速率:2次/s
輸入回路功耗:<0.5VA
顯示分辨力:最高為0.001A,小數(shù)點自動移位,A/kA單位自動切換
輔助電源:AC/DC 85~264V 50/60Hz 功耗<3VA
報警輸出:三相上下限報警同一繼電器輸出,繼電器觸點容量AC250V/2A、DC30V/2A
變送輸出:線性度0.3%,輸出可在0-10mA、0-20mA、4-20mA之間自由切換,負載電阻≤300Ω,變送輸出與信號輸入及輔助電源端口之間電氣隔離
通訊接口:RS485串行通訊,采用MODBUS_RTU通訊協(xié)議
