Overview ARD2F smart motor protectors can protect motors from many faults during the motor running and display the running state clearly and intuitively through LCD.The protector has RS485 remote communication interface and DC4-20mA analog output, which is convenient to form a network system together with control machines like PLC and PC. ARD2F Smart Motor Protector ● Measurement functions are divided into basic measurement (current parameter) and co-selection measurement (voltage, power, phase sequence, residual current (leakage current); ● Start timeout, overload, stall, block, underload, phase failure, unbalance, residual current (ground/leakage), temperature, external fault, phase sequence, overvoltage, undervoltage, underpower, overpower, tE time Motor comprehensive protection function; ● 9-channels DI passive dry node input, signal power supply with built-in DC24V power supply; ● 5-channels DO output, which can meet the direct start, star-delta start, autotransformer start, soft start and other starting modes. Real-time remote control "start/stop" operation of the remote master station can be realized through the communication bus; ● It has standard RS485 communication interface and adopts Modbus-RTU and Profibus-DP communication protocol to ensure fast and reliable communication of the host computer; ● It has a DC4-20mA analog output interface and is directly connected to the DCS system to monitor the field devices. Function Accuracy U, I: Class 1.5 Frequency Range: 45-65Hz Auxiliary power supply AC85V-265V/DC100V-350V SOE event recorder Record 8 fault messages
