2.Integrated process and electrical control
-
PMAC801A provides the main features as below:
1.Measuring: 1 main circuit + 42 branch circuits, Hall sensor zero point calibration
2.DI: 4 status input (dry contact)for Main breaker and Lightning protection switch
1.With the modular design, this product consists of main module, CT module and display module;
2.Over 21 protection functions can be provided;
3.The three-phase current, grounding/ leakage current, current imbalance rate, three-phase line voltage, frequency, power factor, active power, Reactive power, active electrical degree and many other electrical parameters concerning to the motor circuits can be measured;
4.With built-in direct startup mode, bidirectional reversible startup mode, star/delta startup mode, auto transformer startup mode and many other startup modes, users could independently select corresponding settings based on the startup ways of the motor;
5.The controller body can provide 9-circuit switch inputs, for the inputting of such signals as start-stop signal, reset signal and contactor state;
6.By providing 5-circuit relay outputs, this product can satisfy many startup ways and protection actions, together with protection tripping (or alarm) signal outputs;
7.Provide 1-circuit 4-20mA analog output for DCS, with many parameters selectable;
8.Support one-circuit 4-20mA analog input, one-circuit 4-20mA analog output or one thermal resistance input (refer to ordering information for specific model selection);
9.With 32 times of event logging, record device operation data and relevant information at the time of fault; 10.Maintenance and management are convenient and display module or communication software can be used to detect various parameters including electric parameters, motor's operation states, fault information and stopping times;
11.The flexible restart function can realize various startup demands based on parameter
12.settings in case of short-time power outage of the motor's main circuit.
13.Installation is convenient, with standard 35mm DIN Rail-Mounted, simple wiring and pluggable terminals;
14.The communication is redundant, with 2-circuit Modbus communication and supporting PROFIBUS communication protocol; 15.With wide power supply design, AC or DC power supply is in common use.
