Dynalco SST-7000 Digital Speed Switch數字速度開關
Dynalco SST-7000系列數字速度開關和變送器
Dynalco SST-7000系列數字速度開關和變送器可靠,準確的超速/欠速保護,變送器具有高達4個標準繼電器設定點的型號以及LED或鍵盤配置顯示選項。SST7000使用脈沖或頻率輸入來提供準確的4-20 mA輸出或0-5 / 0-10 VDC線性輸出,可直接與機器狀態監視設備或系統接口。可用的輸入隔離選項有助于解決接地環路和信號轉換難題。該設備接受來自可變磁阻和數字速度傳感器的正弦波和方波輸入。使用USB連接的PC可以在幾分鐘內輕松地對SST7000進行編程。裝置上的Phoenix連接器使快速斷開連接和整體布線變得容易。
SST-7000數字速度開關傳輸脈沖或頻率輸入,以提供精確的4-20毫安輸出或0-5/0-10伏直流線性輸出至可編程邏輯控制器或其他讀出儀器,以進行可靠和準確的速度監測。SST-7000 digital speed switch transmits a pulse or frequency input to provide an accurate 4 – 20 mA output or 0-5/0-10 VDC linear output to a PLC or other read-out instruments for reliable and accurate speed monitoring.
SST-7000系列接受脈沖輸入,并為本地面板儀表或PLC模擬輸入卡提供非常精確的4-20毫安輸出,表示旋轉機械的速度。SST-7100還提供對超速/低速條件的快速繼電器響應。應用領域包括工業發動機、渦輪機械和泵的轉速測量和超速保護。SST-7000 series accepts a pulsed input and provides an extremely accurate 4 – 20 mA output representing speed of rotating machinery for a local panel meter or PLC analog input card. The SST-7100 also provides a quick relay response to over / under speed conditions. Applications include speed measurement & overspeed protection of industrial engines, turbomachinery and pumps.
