Product DescriptionARD2F Smart Motor ProtectorGeneralARD 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.Technical ParametersTechnical data of
