AC supply voltage to use for the VAC L / VAC N terminals (see Electrical specifications)
SST-7200D和SST-7400D接受脈沖輸入，并提供4-20mA輸出，該輸出非常精確和穩(wěn)定，溫度變化代表本地面板儀表或PLC模擬輸入卡的旋轉(zhuǎn)機械速度。它們還提供2個“SST-7200（D）”和4個“SST-7400（D）”快速繼電器對超速/低速條件的響應。應用范圍包括工業(yè)發(fā)動機、渦輪機械和泵的速度測量和超速保護。SST-7200(D) & SST-7400(D) accept a pulsed input and provide a 4-20 mA output that is very accurate and stable with temperature changes representing speed of rotating machinery for a local panel meter or PLC analog input card. They also provide 2 “SST-7200(D)” and 4 “SST-7400(D)” quick relay responses to over/under speed conditions. Applications include speed measurement & overspeed protection of industrial engines, turbomachinery and pumps.
