Product Description

Product Description

ARD2F Smart Motor Protector
General

ARD series intelligent motor protector (hereinafter referred to as protector) can perform various conditions such as starttimeout, overload, phase failure, unbalance, underload, ground/leakage, blockage, short circuit and external fault during motor operation. Protection, and SOE fault event recording function, convenient for on-site maintenance personnel to find the cause of the fault. Suitable for coal, petrochemical, smelting, electric power, ships, and civil construction. The protector has RS485 remote communication interface, DC 4 ~ 20mA analog output, and PLC, PC and other control machines form a network system. Remote monitoring of motor operation.
Features1.Measurement functions are divided into basic measurement (current parameter) and co-selection measurement (voltage, power, phase sequence, residual current (leakage current);2.Start timeout, overload, stall, block, underload, phase failure, unbalance, residual current (ground/leakage), temperature,3.external fault, phase sequence, overvoltage, undervoltage, underpower, overpower, tE time Motor comprehensive protection function;4. 9-channels DI passive dry node input, signal power supply with built-in DC24V power supply;5.5-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;6.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;7.It has a DC4-20mA analog output interface and is directly connected to the DCS system to monitor the field devices.
