Product Description
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-channel DI passive dry node input, signal power supply with built-in DC24V power supply
5-channel 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 RS-485 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.
