ARD2F Smart Motor Protector
Characteristics
â—
Measurement functions are divided into basic measurement (current
parameter) and co-selection measurement (voltage, power, phase
sequence, residual current (leakage current);
â— 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;
â— 9-channels DI passive dry node , signal power supply with
built-in DC24V power supply;
â— 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;
â— 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;
â— It has a DC4-20mA analog output interface and is directly
connected to the DCS system to monitor the field devices.
â— Communication: RS485 (Modbus-RTU)
â— Display: LCD display
