★ It has multiple protection functions such as short circuit, locked rotor, overload, grounding, phase loss/imbalance, underload, TE curve, under/overvoltage, startup timeout, acceleration trip before startup, power loss during operation, external faults, etc
★ Measure three-phase current, zero sequence current, three-phase current imbalance, three-phase voltage, zero sequence voltage, three-phase voltage imbalance, active/reactive power, power factor, frequency and other electrical quantities to achieve comprehensive protection of the motor, and have the function of recording protection events
★ Active energy (kWh) and reactive energy (kVARh)
★ Four adjustable protection control output modes:
1. Direct start mode 2, protection trip mode
3. Star/angle starting mode 4, circuit breaker protection mode
★ Wide range AC/DC universal power supply: AC/DC85～265V
★ 1 RS-485 communication interface, Modbus RTU communication protocol
★ 11 switch remote signal inputs: 7 of which have start/stop/emergency stop/communication/display control functions, and 5 relay outputs; One of them is used for device fault alarm output
★ Three phase current measurement and SOE recording, real-time reading through communication interface, protection parameters can be set by display unit and communication software;

☆ Extended display unit: Real time display of measured electricity, on-site parameter setting
Six button digital LCD display unit/seven button Chinese LCD display unit
☆ Dual RS-485 communication interface
☆ 1 programmable DC4-20mA analog output
☆ Restart after losing pressure
☆ Profibus DP communication interface
☆ DeviceNet communication interface
☆ Dual power module PDM-810SY
☆ External zero sequence/leakage current transformer input, measure zero sequence/leakage current
☆ There are two types of current input, and users can flexibly choose according to their needs
1. Specialized small CT input (MT optional):
Below 15A (MT25), 15A-60A (MT100)
30A-90A (MT150), 60A-150A (MT250)
2. Standard CT (1A/5A) is used for 150A and above

Note: Only one of Profibus DP, DeviceNet, and dual RS-485 communication can be selected
