2. Product features
High performance embedded 32-bit industrial-grade microprocessor, high integration, strong performance and fast calculation.
Real-time operating system, high reliability, good real-time performance.
High resolution and large dynamic range multi-channel synchronous sampling module/digital converter with high precision.
Have perfect protection function, all protection function can choose investment respectively or exit, and report to the police action value, the action time of the alarm and trip action value can be set respectively, the action time of the trip, flexible configuration according to the actual demand.
It has perfect electrical parameter measuring function (current, voltage, power, frequency, electric power, etc.), can replace the on-site multi-function power meter.
Support multiple stop control mode (direct starting, two-way starting, star/triangular starting, auto - decoupling, soft starting, etc.).
Support multiple access stop control, display keyboard module stop control, terminal hard wiring stop and communication stop control, can switch by switching switch.
The output of programmable switch quantity and 6 programmable relay can be provided, and can be flexibly configured according to different protection control.
With large capacity ferroelectric memory, all system data, setting parameters and failure record are not lost.
It has built-in anti-flash power module to realize the partial restart control function of the loss (owing).
Support modbus-rtu and profibus-dp multi-bus communication protocol to meet the different requirements of the site and realize running data monitoring and stop control of the motor.
With 25 fault records, the electrical parameter and time stamp can help the user diagnose the fault quickly.
It has 20 stops recording, recording stop reason and time stamp, so that users can check the history of the motor.
It can record the current running time, current parking time, accumulative operation time, accumulative parking time, number of operation times and the number of tripping times, convenient for the daily maintenance and management of users.
With the isolation of 4~20mA input function, the interlock protection can be combined with various transmitters on the field.
The output function of 4~20mA with isolation can be used to select any electrical parameters to correspond to the output.
Large size LCD display, Chinese menu, human-machine interface friendly.
