產品簡介：
Dynalco SST-7400D是一個可編程的PC，安裝在DIN軌道上的速度開關，具有顯示和鍵盤編程功能。它有4個標準繼電器，通過提供可靠的欠速/超速保護來保護旋轉設備免受故障的影響。SST-7200（D）和SST-7400（D）接受脈沖輸入，并提供4-20mA輸出，該輸出非常精確和穩定，溫度變化代表本地面板儀表或PLC模擬輸入卡的旋轉機械速度。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。應用范圍包括工業發動機、渦輪機械和泵的速度測量和超速保護。Dynalco SST-7400D is a PC-programmable, DIN rail mounted speed switch with display and keypad programmability. It has 4 standard relays to protect your rotating equipment from failure by providing reliable under/over speed protection。
