關(guān)于169PLUS-120N-120的常見問題

與169-120N-120電機管理繼電器相比，GE Multilin 169PLUS-120N-120具有額外的功能嗎？

169PLUS-120N-120是阿格Multilin Plus繼電器，因此與169-120N-120相比具有額外的功能。如零件號中所選訂單代碼所示，RTD規(guī)格為120N，這意味著RTD傳感器由120歐姆的鎳組成。Plus型號帶有額外的兩個RTD輸入。這些RTD輸入的顯示精度為正負2°c。169 plus-120n-120具有由零件號指定的120 AC控制電壓。頻率規(guī)定為50/60赫茲，最大功耗為40伏安。
除了額外的RTD輸入，169 Multilin Plus型號還帶有兩個輔助繼電器。169 Plus型號能夠監(jiān)控和記錄電機統(tǒng)計數(shù)據(jù)，如電機啟動次數(shù)、繼電器跳閘類型和電機運行小時數(shù)。169 Plus還可以通過記錄冷卻速率、加速時間、負序電流發(fā)熱系數(shù)來適應特定的電機，并使用這些數(shù)據(jù)為特定的電機定制電機保護。相比之下，基本169模型僅限于學習電機浪涌電流。GE Multilin 169 Plus繼電器，如169PLUS-120N-120，還包括備用輸入、差動繼電器和速度開關(guān)。Plus型號配有RS 422端口，以便與計算機或可編程控制器通信。MMY30-R-1-C-1-G - GE GENERAL EASTERN - Trace DewPoint Loop-powered Transmitter w/Integral FlowCell
