DMTC96(96X96外型) 溫度電驛 變壓器保護器 49RELAY
FEATURES:
DMTC96主要針對中小型乾式變壓器溫度保護設計，具備4組白金屬電阻溫度裝置輸入訊號 (RTD PT100)，狀態接點輸出(警報/跳脫/第四組溫度警報) 額外2 組接點輸出(接點容量10A)啟動橫軸風扇，超大高亮度顯示，能在遠距離清楚看到顯示溫度及高分貝蜂鳴器，能快速傳達變壓器故障資訊，智能判斷電錶故障或感溫棒異常或斷線時，保護器會發出報警及接點輸出，但不會執行跳脫輸出，確保系統正常運作，同時具備標準RS485 Modbus輸出通信介面，通信、監測整合

◆High isolation ability
◆ Circuit fault protection.
◆ In the event of a circuit fault, the protector will forcibly activate the fan to perform heat dissipation.
◆ Open circuit warning and power failure protection.
◆ When the temperature sensor rod is abnormal or disconnected, the protector will trigger an alarm and display the "Err" signal, but the Trip contact will not activate.
輸出， 不會造成系統跳脫
◆ Output functions: 4-20mA output (Optional), RS-485 MODBUS RTU output.
◆ All outputs are designed with high isolation, allowing for long transmission distances.
Standard equipped with RS485 functionality.
